Nice video guys, as always! Only one thing ... TDS meter in fact mesure water conductivity (EC) and then convert it in TDS using a conversion factor. This factor value in usually 0.5, called "sodium factor" - assuming that all hardness is due to NaCl. But there are other conversion factors like 0.7 called "442" (40% Na2SO4, 40% NaHCO3 and 20% NaCl). So, is better to refer at EC instead of TDS.

[@GreenAquaShop]

Love this, thanks for the clarification! We do refer to TDS because that is what everybody does in the hobby. But you're right, EC would be better.

Hi, I have a notes about the kh in water 1) In the Amazon River there is no kh in water and as Tommy said in a previous video, changing the ph around 1 degree in the day is not a problem. 2) I do not think that the ph fluctuation/crash is easy, as evidenced by the need to inject tons of co2 into the tank to lower it by one degree 3) There is an article on your official website mentioned in the case of using active soil. It is sufficient to use the gh+ thanks

[@BloodyMarryShrimp]

@@TheDenny188 I always thought the value for potassium was 50-10. You wrote 20-30. Why so much? Is it better for the plants?

[@GreenAquaShop]

Potassium is the only macro element that is not being produced by the fish and plants consume it in the same way they consume nitrate. Therefore, all hobbyists and manufacturers found (regardless of their rich or lean fertilizing style) that adding lots of potassium will benefit plant health, and not adding it will result in plant issues. Nitrate and Phosphate are also needed, but even if you measure zero, you should know that these elements are continuously produced by the filter and instantaneously uptaken by the plants, that's why you measure zero - or close to zero values - with lean fertilization.

In the long run, it's generally easier to adapt your fish and plants to your tap water than adapt your tap water to your fish and plants. Stability is important and chasing parameters up and down and all around will create stress for your livestock and stress for you.

[@GreenAquaShop]

Yes, right! I was actually thinking a bit when talked about cooling the water with slightly cooler new water when the temp raises, as that is a change that would stress fish, but I left it in.

[@pianobench6319]

This is true. Users vary the amount of additive and water they take out. I accomplish my water conditioning by mixing it all in a separate container. A 36 gallon trash bin which I fill up to the same mark each time. Then I add in my water conditioners that I’ve measured out. Repeat the same until it’s all very stable. Ideally I’d have a huge 2000 gallon external clean tank and do all my water work in there. That will be the most stable. But we each do what we do because it works!

[@ИгосПро]

Thanks for the video. It was really useful. Could you tell me which way is better - set co2 round the clock (for stability ph) or when the light is set only?

[@GreenAquaShop]

We're not the fan of the 24hrs injection. Except when you have a pH controller in place.

[@ИгосПро]

@GreenAquaShop whatever, if you have a ph controller, you should set co2 24hrs for stability. You mean I should set the co2 when I got the ph controller only? I can keep under control by bubl counter. The question is, do I need to keep supply co2 24hrs or is it not necessary?

[@GreenAquaShop]

Some use the 24-hour method, but this is used for keeping sensitive species like shrimp. We do not see any advantage to it. pH controllers are different, as you can set a pause period and hysteresis and monitor and turn off CO2 when it is too much. The manual method just pumps CO2 without real control.

[@christopherfassett9973]

I always love your videos. I appreciate the difficulty in attempting something like this, and I'm always on the lookout for good water chemistry videos to recommend to beginners. I think this one comes the closest to what I've been looking for in the decade or so that I've been helping others in the hobby, but I have just a couple nitpicks. Now, I totally get the point early in the video that you can see success with different parameters, but that this is just what you've found works well. I totally understand and respect that, and while there are lots of little details that could be added, you're trying to not make a 3 hour long video 😂 That being said, there are just two reasons I can't recommend this video: 1. The Redfield Ratio just needs to die, lol. It's very misunderstood. It's the ratio of C:N:P (160:16:1) in marine phytoplankton, as determined by a guy named Alfred Redfield in the 30s. It's not relevant to freshwater (which varies much more in nutrient levels) and it's not relevant to macrophytes (which tend to resemble terrestrial plants more with an average ratio of 2-12:1... yes, several aquatic and terrestrial plants have been shown to contain a 2:1 N:P ratio). Finally, those amounts are representing atomic N and P, not NO³- and PO⁴+. The regular Redfield Ratio (16:1) as calculated for NO³- and PO⁴+ would be 23:1, which isn't even close to anything people actually do Keeping N and P low is a good strategy for nature-style aquascaping, which is usually heavy on hardscape. Rich fertilization is really only for Garden-style tanks, with >80% of the substrate planted with fast-growers. So as a strategy that works for you, that totally makes sense. The other point is the KH thing. If 2 dKH works well for you, that's great, but 0 dKH does not cause wild pH fluctuations or melting plants. That's a myth that's based on a misunderstanding of some real concerns in natural systems. The whole pH crash thing isn't really a thing either, unless you're talking about an aquarium that goes >1 year without a water change. To explain it fully requires a *lot* more detail than I'm going to put into a KZbin comment, but I'm happy to talk about it any time. I speak as someone who has run a very happy and productive tank breeding hundreds of Neocaridina shrimp with a baseline pH of 5.5, down to 4.5 with CO² injection. But also, Dennis Wong (2 Hr Aquarist), Tom Barr, Gregg Zydeck, and many others use 0 dKH to grow plants that can't be grown in higher KH. The only plant I've *ever* seen that struggles in 0 dKH is Rotala ramosior. Every other plant I've ever grown is either indifferent or actively prefers 0 dKH. I think Marwen was harsh in his assessment, but this is very well known among the best plant growers in the hobby (many of whom are quite poor at aquascaping, lol) If not for those two details, this would become another go-to video for helping people understand water parameters. As it is, the only source that I've been able to recommend unreservedly is Dennis at the 2 Hr Aquarist Generally, love your videos, cheers!

[@fabioprata9539]

Sorry man, but you can not discredit other people’s experience on the topic and their learning from decades on the field. For example, from their experience and myself we can observe that no KH on new setup tanks does melt plants. It is also fact that the PH will fluctuate as crazy if you are injecting CO2 at day. That is chemistry, not opinion.

[@christopherfassett9973]

@@fabioprata9539 That sounds great and all, but in this case, to do so discredits the experience and expertise of people like Tom Barr, Marian Sterian, Xiaozhuang (Dennis) Wong, Sudipta Shaw, Joe Harvey, Winston Sumogod, Omid Niavarani, Vin Kutty, Gregg Zydeck, and many others. If you don't know who any of those people are, you should google them. Given your placing in the IAPLC (congrats, btw), surely you're familiar with at least some of them. Some have placed in aquascaping contests, some have judged, some have PhDs in argology and enzyme biochemisty, some of them just grow plants that no one else in the world can grow (or can grow to their highest form). Now, as far as the chemistry bit, I'm sorry but you're right, there is no room for opinion there. It's science. We can go about it two ways: 1) the scientific method. Have you ever run a 0 dKH tank? if you haven't, how do you know? I have, and many others have, and we don't see pH swings. 2) we can understand the science behind it, and where the misunderstanding comes from, because it *does* have a basis in real science. It's just misunderstood. I have a bit more time on my hands today, so I'll go ahead and write a little chemistry lesson. So, a conjugate acid/base pair is a pair of molecules that differ by a single proton (Hydrogen is the simplest atom, consisting of a single proton, so in this context proton and hydrogen, as in "potential of Hydrogen", are synonymous). A unique characteristic about conjugate pairs is that they don't destroy each other. So you can add a ton of both of a pair to a solution, and the acid neutralizes any bases, and the base neutralizes any acids, and they naturally reorganize to an equilibrium with each other, so the pH doesn't move. That is a "buffered solution". That's what we use to calibrate pH probes. Now, carbonic acid > bicarbonate > carbonate H₂CO₃ > HCO₃⁻ > CO₃⁻⁻ (Or CO₃²⁻) Each minus represents a missing proton, because it can accept a proton from the water. That's what makes it basic. They are a conjugate trio. Now, carbonate hardness is supposed to represent the total bicarbonate+carbonate in solution. Those are a conjugate pair, so that must mean KH=buffer, right? Well, every buffered solution has a target pH and a useful range (where you can tweak the recipe to target any point in that range). For example, pH probe calibration solutions are buffered solutions, that way, minor cross contamination during calibration doesn't throw the whole thing off. But there's a limit to how much acid and base a buffer can neutralize before it is exhausted. These are Acid/Base Neutralizing Capacities (ANC/BNC), and the total buffering capacity is always equal to the lowest of the two. You can make a bicarbonate/carbonate buffered solution. Its main target pH is 9.6 and its useful range is 9.2-10.6 If your pH is

[@christopherfassett9973]

Oh yeah, one red flag from the video is that they specifically say that the only time they recommend measuring KH is when plants are melting. But if you only measure a parameter when conditions are poor, how do you know that the parameter has actually changed? If you want to try and correlate parameters, you need to test frequently so you have a baseline to compare it to. Even then, instability of *any* sort can induce melting in more finicky plants. This includes KH, GH, nutrients, CO₂, temperature, etc. I just really struggle with the KH section If you're growing easy plants, like Green Aqua does, then you have a much wider range of tolerance. For those of us growing Eriocaulon, Lachnocaulon, more challenging Syngonanthus, Hygrophila araguaia 'Chai', Paepalanthus, Tonina, Centrolepis... this won't cut it. And that's fine, they're speaking within their experience. The KH thing is the only really big issue I have because it's increasing work and cost, increasing the toxicity of ammonia, and making the tanks less forgiving than they would be if they just left out the KH

[@christopherfassett9973]

Oh, well... my super long comment explaining the science behind it has disappeared 🤷‍♂ Not sure if it was a some automated filter or what, but oh well. That's why I don't usually bother with youtube comments for that kind of thing. If you want the actual science behind it, you'll have to find me on a different platform, or spend a significant time researching it. If you want a head start: learn about conjugate acid-base pairs, buffered solutions, and the useful range of a carbonate buffered solution. If your pH is less than 9.2, there's no buffering, just alkalinity, which is *not* the same thing.

[@GreenAquaShop]

Thank you,@@christopherfassett9973, for your detailed explanation about the role of carbonate hardness (KH) and its buffering capacity in aquariums. You emphasize that below a pH of 9.2, the buffering capacity of bicarbonate/carbonate systems is essentially exhausted, rendering KH ineffective at resisting pH swings in that range. However, the situation is a bit more complex than it might appear at first glance. I discussed your comments with my father, (who is a chemist, as I mentioned in the video) and he points out that all conjugate acid/base pairs, including the bicarbonate/carbonate system, do exhibit buffering effects, and this buffering capacity is influenced by the metal ions present-such as sodium (Na⁺) or calcium (Ca²⁺). Specifically, when calcium ions are involved, the buffering effect occurs at a lower pH range compared to when sodium ions are present, due to differences in how these metal ions interact through hydrolysis, which affects the resulting pH. Carbonic acid (H₂CO₃), being a weak acid, only slightly acidifies the environment. However, in the presence of calcium bicarbonate (Ca(HCO₃)₂) and calcium carbonate (CaCO₃), the pH can increase because the hydrolysis of these salts produces calcium hydroxide (Ca(OH)₂), a base typical of slaked lime. These processes are part of equilibrium reactions, and the buffering capacity depends on the concentrations of these dissolved compounds. The solubility of CaCO₃ and Ca(HCO₃)₂ plays a crucial role here, as does the addition of CO₂, which shifts the equilibrium towards more carbonic acid and bicarbonate, affecting the pH balance. While it's true that the buffering capacity has its limits and can be overwhelmed - especially with significant additions of CO₂ - the KH does contribute to buffering within the typical pH ranges found in aquariums (usually between 6.2 and 7.5). The effectiveness of this buffering is governed by the concentration of the buffering agents and the specific chemical equilibria in the tank. Overextending this capacity can lead to pH fluctuations that might affect aquatic life, but it doesn't mean that KH has no buffering effect below pH 9.2. Therefore, your view seems a bit oversimplified regarding the buffering role of KH in aquarium settings. I appreciate your insights and the opportunity to delve deeper into this complex aspect of aquarium chemistry. Understanding these nuances helps us better manage our aquariums for the health of both plants and fish.

[@ubrosso]

Aquavitro Carbonate is giving me too much phosphate to bring my KH to 3 as my water source is almost zero. So it adds up to natural food phosphate. Phosphate is being the hardest for me to lower. And a question I have is if in planted tank ph range "acid by day and basic by night" could be used for acid loving fish. But cause if I acidify the water for no basic ph time the amount of co2 needed to inject would lower the ph to a point it would crash the cycle as nitrifying bacteria suffers in prolonged acid, right?

[@johnwayneaquaria8770]

Nice! Well said. As far as PH my natural from the well is about 8.5-8.8. I have driftwood in my tanks brining it down by maybe .4 or so. as far as what I’ve found fish really only care about a stable PH so long as it’s not entirely extreme.

You should not have TDS 120 with seiryu stones "from the beginning" if you have made a 50% water change with TDS 7 RO water. You should see something like TDS 50 and then remineralize that to 120 and watch the TDS rise to 180 in a week or so, after which you do another TDS 7 water change, etc.

I understand the use of tap water before the resin softener but in case of a RO System after the water softener system? or should i still connect the RO System before water softener (with resin) system?

[@GreenAquaShop]

Good question, and a bit complicated to answer. If you connect the RO before the Resin system it would work as usual, so that's what I would personally do. If you connect it afterwards, you are removing the salts that are produced by the central water softener so I see no point in the ion exchange when you are removing the result anyway... With that said, your central softener might have some prefilters too, which would keep your RO prefilters (and membrane) cleaner - theoretically, so that's a pro. But it sounds like a bit of waste to me. But it won't hurt the RO probably... One thing is sure: we connect RO-s before the waste water with clients.

[@MOMENTSbyGabriel]

@@GreenAquaShop yes i agree, in my particular case i can technically connect the ro before the central softener… but that would be in the basement and it will becaome cumbersome to carry the RO water tonthe 1st floor 😅 that’s why i have it connected after the softener since it’s closer to the aquarium, and was wondering if this might be an issue or not.

[@hampusberglund4368]

You are missing an important point regarding oxygen. At night, or when the lights are off, plants consume oxygen. It’s incredibly important to use an air stone during this time or raise the outflow to create more surface agitation. I overlooked this for years and could never understand why my fish were gasping for air in the morning, even though all my parameters were perfect. Then I read about it in an ADA guide on creating an aquarium

[@GreenAquaShop]

Yes, you are right, thanks so much for clarifying. That is indeed important in most cases, and ADA does it too. We don't do it, and found no issues, but night-time oxygenation sure helps and is strongly recommended by Green Aqua too.

[@christopherfassett9973]

Eh, that's really only a concern if you have poor flow to begin with. Yes, autotrophs consume oxygen at night as they break down the sugars they made during the day, but the effect is much smaller than the O² produced during the day. Many aquatic plants also use Crassulacean Acid Metabolism to continue consuming CO² at night, storing it in vacuoles to use when the lights turn on (succulents also use CAM, but for a completely different reason, they use it so they don't have to perform gaseous exchange during the day when the heat would cause them to lose more water). Anyways, the point is that if you have halfway decent surface agitation, good surface skimming, and good vertical mixing of the water column (all of which is easily accomplished with a set of skimming lily pipes), then aeration is unnecessary at night. The one exception can be of you have a large algae bloom, particularly planktonic (green water algae/cyanobacteria). We cannot comprehend the number of individual algae cells floating in such a bloom, and they absolutely can deoxygenate the water at night.

[@detlefh.7090]

You should airate at night if you grow plants in great quantities that produce lots of oxygen during the light period e.g. Riccia (they in turn can deprive oxygen at night to levels where not only fish start to suffer). The same is true when your tank does not reach 100% O2 saturation during day time hrs which is more likely with poor plant growth and/or heavy bioload (shrimp and fish). Also, you don't sense when your filter bacteria suffer from oxygen depletion (keep in mind that they are active at night as well). In general it is much better to err on the safe side and airate at night no matter the tank condition.

[@Saxonwomen]

Just need the surface of the water to be agitated, my tanks are very heavily planted & have never had a problem with this.. if temperature is too high that can cause the fish to galp for air at the top on the water..

[@suffysdave]

Can you please always mention the units when measuring TDS? Most use ppm, but in my local store they measure uS/cm (which is technically conductivity). It is the TDS x 2. This can lead to confusion.

Can you make a PDF of the ideal parameters chart?

[@2ksharp]

How do you keep the GH in that range in scapes you use lots of seriyu stone? I have a nano tank with seriyu stone and i water change with RO of 7 GH. Within a few days my GH goes up to 13-16 and thats where it stays until I do my weekly water change. I cannot seem to keep a low GH at all

[@GreenAquaShop]

Yeah, we do have fluctuating GH (TDS) too, there's nothing you can do about that, except more frequent water changes if you have the energy. We don't but we found that after some time the amplitude decreases, when we start with TDS 120 after water changes we get to 170-180 by the end of the week, that's not very bad, at least that's what we found.

[@AquaticJourneyman]

What I still don't understand and seems like a lot of other people don't either based on forums is how to have a healthy tank while using rocks like Seiryu stone. Stones like this make your water parameters out of whack. How do you keep stable parameters with rocks like this? It's the one thing I was looking for that wasn't touched on.

[@la_nella]

Biggest thing I would say is water changes are your friend. If it’s raising GH KH anything , you can always for example use RO water to “reset” those parameters. That’s why many people, especially those who want to grow more sensitive plants, or those who do more advanced things do. Since the RO would essentially be pure water , you can then start off at all 0 values , and pH being neutral.

The part about low/zero KH being bad in planted tanks is a myth that has been debunked countless times. There are many amazing planted tanks and aquascapes running on zero KH. Low or zero KH is great for plants under CO2 injection. (The bit about zero KH causing plant melt in a new tank is also nonsense.) The part about phosphate being above 0-0.2 ppm causing algae proliferation in a planted tank is another myth that has long been debunked. Your knowledge on water parameters for planted tanks seems quite outdated. Please do your research before spreading such old myths to new hobbyists.

[@GreenAquaShop]

Come on, guys, did you hear me saying in the first part of this video, that sticking to these values is only something we found works for us and many aquascapers throughout the world that we are in contact with, and that other values might also work for people? I see no reason for using words like myth, nonsense, and living in the past in comments. I'm 51 and I read too many forums and comments that were separating the people in the hobby into groups that fight each other over nothing. Thanks for watching the video, you are great! Peace

[@christopherfassett9973]

​@@GreenAquaShopI think that's a fair response, but some of the top growers in the world have been banned from TPT in the last couple years for saying 0 dKH was fine. One particular moderator (username: somwhatshocked) went on a whole power trip about it, even though the whole thing is a (very complex) misunderstanding. 0 dKH is not harmful. If it was, we would have virtually no plants/fish from places like the Rio Negro, the Pantanal, or from 90% of South and Southeast Asia, where pH ranging from 3.5-6 are totally normal. Yet these places have some of the highest aquatic plant diversity in the world. The point being, people are upset because you've (inadvertently or not) fed one of those issues that is actively ripping TPT apart as we speak. It was a huge loss when Gregg Zydeck's 200+ page, 4,000+ post journal was deleted, all because in several years of running 0 dKH, he never saw a pH fluctuation. It's just one more entry in the long-running category of "wildly unnecessary drama", lol

[@la_nella]

I understand both sides of this. Maybe some things were stated wrong , but they did also say that swaying from these parameters would not cause a problematic tank. As for Dennis , he did create a statement , which I really like. Here is the statement: There is no need to test boundaries if all they do is grow easy plants. As a business, selling scapes with easy plants is the way to go, no client tank with limited servicing is gonna grow a Hygrophila chai or Erios. Their focus is on hardscape and low maintenance. Why have higher than 0.2ppm PO4 if you're just growing Java fern and mosses. Why have low KH if not growing any picky soft water plants, they could use Seiryu rock on every tank and it'd work out the same. Their advice reflects the expertise with the type of scape they do (hardscape focused, easy plants). Looking to them to in-depth chemistry advice, is like looking to movie celebrities for nutrition advice.

Hello. What to do if Amazonia ver-2 soil is "eating" all po4. Dosing 2-3ppm per week. Tested with JBL and Salifert tests. Should i continue dosing until i see some po4 in the test? Or just add 0.2pmm as you recommended and skip tests? Fertilizing aquarium by EI method. Thanks.

[@GreenAquaShop]

If you're on EI you do not need to worry about it. Most aqua soils take up the PO4 in the first few months not only Amazonia.

[@AshTaw]

Sir, I am your subscriber from India 🇮🇳 and want to know if I can use Chira stone is also known as laterite stone in English. Laterite is a type of soil and rock that is rich in iron and aluminum. It is commonly found in tropical areas that are hot and wet ( Ratnagiri sindhudurg , Karnataka ) . . Will it effect my Fish or plants ?

[@GreenAquaShop]

It depends, no experience with that stone, but if it leaches too much iron, you can have issues with the iron reacting with phosphate and precipitating in your filter. So I would avoid it.

[@joaorodrigues6526]

What happens when the KH is higher than the GH?

[@nature_explorer8143]

Just saying. There are many beautiful planted tanks with 0 KH.

[@GreenAquaShop]

Just saying, while there are indeed many beautiful planted tanks maintained at 0 KH, they often have higher pH levels or other balancing factors that mitigate the risks associated with low KH. In our AI-Scaper's algae risk evaluation, we consider these nuances by using a percentage-based risk assessment rather than a binary outcome. Even with a 40% risk of algae, for example, there’s still a 60% chance that the tank will remain beautiful and algae-free. This approach was designed precisely to avoid such polarized discussions by providing a nuanced view of aquarium health. I love how this video has sparked a vibrant discussion on aquarium chemistry, reminiscent of debates typically seen on other platforms. There's really no need for conflict; we’re all here to learn and share our passion for aquascaping. Peace.

Question: I have almost RO water (26 TDS out of tap), my tanks range 300-500 TDS. Is there a way to determine what the Dissolved Solids are that are being measured. I know salt spikes TDS, so my theory is it's brine shrimp salt, which I also add some Epson salt to. I know that pretty much blows the Green Aqua standards out of the water, haha. My fish are happy, my tanks are beautiful and full of plants, so I've never stressed about the high TDS. My secondary theory is that salt is good for fish for a number of reasons, so I don't want to rinse my brine shrimp. If you use a TDS meter on brine shrimp solution (2 tablespoons per liter salt and teaspoon of Epsom salt) it shows 9999 TDS. I will answer my own question because I have salt meter test strips for my pool, but I'm still wondering if others have this high TDS issue they believe is brine shrimp salt.

[@GreenAquaShop]

Wow, so many numbers. :) Anything that changes the conductivity in the water also raises TDS!

[@danielheckmann3173]

So I’m not crazy for reading 0 ppm Amm, 0 ppm No2 & 0 ppm No3. Could someone explain exactly what is happening in this process? What if my No3 never fluctuates or rises above 0?

[@lawrencelikaiso]

There are a few scientific errors in the video. I'll address some and provide more information on others. 1. Silicon is a beneficial plant nutrient. It promotes plant growth, improves cellular structure and increases disease resistance. This may be part of the reason why plants grown using tissue culture are small and weak, bc the nutrient solution lacks silicon (amongst other essential and beneficial nutrients). 2. Potassium does not need to be 20-30ppm. This is likely far too much as aquatic plants don't need it. It's primary function is osmoregulation, as is sodium (which was not addressed in the video) which is more important for animal health. If sodium is lacking, it can lead to poor health and premature death of fish and shrimp. 3. Nitrate excess can prevent certain types of alga (e.g. filamentous types) from growing. That's why aquariums with high amounts of NO3 tend to not have these alga. When nitrate is excessive, plants (and alga) stunt and grow deformed due to a molybdenum deficiency. Molybdenum is required for nitrate reduction so fertilizing exclusively nitrate nitrogen can result in molybdenum deficiency sooner. The reason filamentous alga die under high nitrate is due to insufficient Mo . Fertilizing Mo under high nitrate will allow plants (and alga) to grow. 4. Phosphorus should be balanced with nitrogen. An N:P ratio of approximately 10:1 is optimal for healthy plant growth. 0.2ppm of phosphate = 0.067ppm of phosphorus. Using the 10:1 ratio, that means nitrogen would be 0.67ppm, which is ~3ppm of nitrate. Increasing the amount of P can signal to plants (e.g. Anubias and Bucephalandras) to flower.

[@lawrencelikaiso]

@26:41 the filamentous alga's wiry and clumped growth indicates a molybdenum deficiency. Under sufficient Mo, the alga grows straight and thick like hair.

[@detlefh.7090]

The numbers aren't of particular interest for most plants but you should explicitly tell folks which units you are talking about concerning TDS. Do you mean ppm (dissolved solids) or microS/cm (conductivity)?

[@GreenAquaShop]

You are absolutely right, that's what my father told me on the phone after he watched the episode. :D Yeah, TDS is measured in ppm but the test itself measures conductivity and then converts it.

[@detlefh.7090]

@@GreenAquaShop Just to make it clear for once and for everyone :) The numbers given by Green Aqua are ppm (ppm x 2 equals microS/cm). At least this is how I grasp your reply.

It only makes sense to measure TDS if you use RO water, which is their case. In Brazil, water is normally very soft and it is not common to use RO water in planted tanks. So measuring this will make no sense at all.

[@GreenAquaShop]

Yes, you are right, this is why I said in the video, that knowing what you have matters, and it doesn't hurt to check sometimes, because values can shift with time - we know that from experience. But there is no need to get "all-chemist". LOL.

In my opinion, water quality parameters are only a part, the most important thing is still the temperature in the lake or outside the environment 20-22 degrees is a beautiful tree.

[@GreenAquaShop]

Absolutely, water quality parameters are indeed just one part of maintaining a healthy and visually appealing aquarium. While temperature is crucial, with 20-22 degrees Celsius often being optimal for many plants, it's important to recognize that no single factor can be deemed the most important in isolation. In aquascaping, every element from lighting and substrate to CO₂ levels and water chemistry contributes to the overall balance. That’s exactly why we developed AI-Scaper-to provide a more holistic view of aquarium health through its risk percentages. This tool helps aquarists understand that while one parameter might not be perfect, the overall balance can still support a thriving, algae-free tank. By looking at the bigger picture and managing risks collectively, we can achieve beautiful results without getting bogged down in specifics. Let's enjoy the diversity of methods and views in this hobby. Peace.
