I have a off topic question and dont know where to ask but figured I would try here.... will carbon take out the plant fertilizer, plant food and iron out of the water? I just started thinking about it if it takes medication out of the water why would it not take easy green and iron out of the water too

[@anthonybrown4892]

Any help or guidance would be appreciated

[@silverleaf15]

Yes, I think in one of Cory’s planted videos or when he was taking about filtration, he stated that he never uses carbon because it takes out organics that the plants use to grow.

[@VyvienneEaux]

Here's an observation you might like to think about before deciding to reduce water changes: Many shrimp breeders (myself included, though I'm a novice) have anecdotally noticed that increasing water change frequency has increased shrimp breeding rate despite often causing no noticable change in parameters we can test for. The water changes are temperature-matched and often dripped back into the tank slowly, so I doubt this effect is caused by water change-induced molts. My hypothesis (I have a background in biochemistry) is that there are some exocrine factors accumulating in the water over time that may be secreted by the shrimp.

[@davidsamsell2031]

I also live in Denmark, I usually leave the water to sit for 24h before I change it. I was told chlorine in the water will evaporate within that period. First time I hear that there is no chlorine in tap water. Can you elaborate on why there is no chlorine in Danish tap water?

[@svenwernersson2931]

@@stamentonchev It is basically because most of the tap water in Denmark is groundwater which means there is not a lot of bacteria in the water so it does not need to be treated with chlorine. Sorry for the lack of commas I do not know how to use commas in English. I too come from Denmark.

[@angelfishhaven]

A couple other points I would add is that even if you know what level your city is treating at do not think that you are safe. During large storms or other events the cities will temporarily increase dosage to treat something they found in the water source. If all of a sudden the chlorine smell increases you may need to treat more. Chlorine spikes have cleared out entire fish rooms. I also do not recommend changing water in all your tanks on the same day if you have several for that reason.

[@TheRflynn]

AngelFish Haven certainly true in Dublin, Ireland

[@sed6]

I was thinking this also, thanks!

[@peadookie]

Interestingly, we have a bunch of snow melt right now and I coincidentally noticed a strong chlorine smell in our tap and wondered if they adjusted for additional runoff. Now I know, thanks!

[@globalist1990]

Lots of other things as well like ammonia. It's not just chlorine. Almost no one mentions this on other videos I've watched, mostly they advise to test the water on the tank already. Well the fish are in it, they're doing fine. What about the water you're just about to add? You need to know it's good.

[@AquariumCoop]

I want to clarify that I only run into *Chlorine* in our water that is why with smaller water changes I can get away with not using dechlorinator. If you have *Chloramine* even with small water changes you'll need to use a dechlorinator.

In 50 plus years of fish keeping I have never owned a test kit...back in the day we never did a water change...tank lids were made of I want to say steel...and had florescent tubes in them so you would lose a ton of water and you would need to do huge top up all the time...and my tanks has so many plants in them you could go weeks without seeing some fish...my first tank was home made..150g...we also made the undergravel filters and box filters... you'd have to take the fish out every 2 years to re putty...the fish stayed in a bucket...and to be honest we rarely lost a fish...we had nothing to dechlorinate we just let the water stand....I do dechlorinate now but I still let the water stand in the room the tank is in for a good few hours...I water change every week because the fish love me pouring in the clean water and wait to play in it..I see KZbin videos about now with no water changes or few water changes...water changes for me are a time I can make sure there are no dead fish..cut back plants let the fish swimming in the filter outflow...they just love that heavy flow of bubbles into the tank...it's not something I plan to stop doing weekly yet...

[@bookmouse2719]

Yes, I use to let the water stand in buckets for a day to get rid of the chlorine, many years ago. I have air stones and some plants but no fancy co. Mostly the hardier fish seem to do well with my every other week water change of 30% and dechlorinater.

Thank you for going into such detail here. I have found, for my tank, the use of an undergravel filter, two airstones, and an over the top edge filter, and a few amazon sword plants, my tank doesn't need water changes much AT all! It creates a natural flow through water "pond" that balances itself.

[@Blakitoo]

How large is your tank?

[@roxanneortegon3240]

Love all of this information! I only do a water change once a month. And it’s not even 50%. Noticed when I did it more than that - my ammonia would spike all the time. And cause stress to stock. I also realized that I cannot not do a sponge filter clean AND gravel vac on same day or even week. I wait two weeks in between. And yes, I use tank water in a bucket to clean sponge.

[@kpov2533]

It's because everyone says you need to constantly be doing water changes and cleaning your filter. It's not necessarily true depending on your tank setup. The beneficial bacteria is doing the work and plants. So if you do big changed the bacteria can't catch up fast enough

[@JoeSmith-ni9ej]

I've been keeping fish (mostly new world cichlids) for over a decade. Honestly, I found less water changes is the most beneficial. My fish seem less stressed, and don't get sick. I usually just clean the filter sponges and top off evaporation with dechlorinated water. I run an airstream or 2 depending on stocking and usually have a canister and hob for bigger tanks and just a hobfor smaller. I learned this after the first year or so of fishkeeping. It happened by accident. I went through a bout of depression and couldn't be bothered to do the weekly water changes, especially on bigger tanks. I noticed no change in my fish behaviors and I noticed they weren't getting ich. It felt like every other water change no matter what I did resulted in an ich outbreak. I know this is controversial, but I wouldn't recommend this for people who are new to fishkeeping (since you may not be able to see subtle things that are wrong with your fish yet) or are keeping more sensitive fish species. Your fish will tell you if something is wrong. So unless fish are not behaving their norm I leave them alone and enjoy their company.

My w/c routine depends entirely on the aquarium - my 30L with a male Betta and nerite snails, typically has a 30% w/c bi weekly, onn the flip side, my 400L micro fish community has a 75% w/c once a month. I do dipstick tests weekly, if the stick indicates an issue, I break out the NT Labs full test kit to pinpoint the issue. It really just depends on the size or the aquarium, stocking level, what it's stocked with, feeding routine and the scape. And being Scotland, we typically have very soft water, although I haven't tested the chemical composition of the tap water here since they changed from chlorinated to chlormination (chlorine and ammonia added) so need to get round to that. I do let the water sit for 5mins before adding it the tank.

Then a nurse told them it could be a reaction to chloramine and recommended dissolving a vitamin C tablet in his bath water. It worked.

[@TheRuturaj001]

Great overview. I was always confused about difference between pre treating water and adding conditioner to tank then add water, found out that some has asked this to CEO seachem and his reply was "some people prefer to just add the new untreated water directly to the tank... if they do that then we recommend the amount of Prime they add be based on the total gallonage of the aquarium rather than just what they added. The "extra" amount speeds up the rate of removal."

[@joka7316]

I work for a water co. The residual chlorine (CL-) varies due to how far you are from the point of injection into the pipeline. CL- is a fragile molecule and decays rapidly that is why some areas that have large systems use chloramine . Your local water co. or city will post testing results on their website that should give you an idea as to what the water has in it.

Best thing I ever did for my aquariums was switching to sodium ascorbate (vitamin C) to dechlorinate! I used (and still use sometimes) Seachem Prime and think it's a great product but I noticed that my fish would flash a lot after a water change. That stopped when I switched to sodium ascorbate and my fish health improved even more overall. And bonus, you only need a small amount.

Great tips. I like to use a dechlorinator/water conditioner that also includes a chelating agent. Chelating agents bind metal ions in a soluble form which can be absorbed by plants or changed out during water changes. Free metal ions are much more toxic than chelated ions. However chelating agents will pull down Oxygen content of the water slightly because they are anti oxidants, they use Oxygen in the chelating reaction.

I always learn from your videos. I have kept fish for years and just went with the idea on prime that more is ok because the bottle says you can double it. Somehow I was unaware that the ammonia is only bound for up to 24 hours. I have even thrown a capful of prime in if I know my nitrates/nitrates might be getting too high and I can’t do a water change for a few days. I guess that did nothing to help my fish 😐. Luckily my tanks are pretty stable and I don’t usually have to do weekly water changes but now I know I need to change the way I use my dechlorinator. Ty!

[@JeffreyGVny]

@Katherine. If you constantly have ammonia, your tank is not properly cycled or maybe you’re overfeeding?

[@Miguelspl150]

The chemical is gone in a day so it’s not treated by the time you do the water change. Also if you’re using carbon you don’t need to use the chemical. The carbon will remove it and guess what will remove the ammonia left behind? Your cycled filter. I only use prime if nitrate gets bad. In a cycled tank ammonia and nitrite is none existent and if you add some form your tap the ammonia will get cycled out with the live bacteria in your filtration

[@Miguelspl150]

JeffreyGVny even if he overfeeds there should be no ammonia unless he doesn’t have biological media. A cycled tank removes the ammonia and makes nitrites and then To nitrates so if you overfeed you end up with high nitrates not ammonia.. i used about 2.5 inches of sand and lots of lava rock and I can go months with no water changes or filter maintenance. I’m over 6 months since I done a filter maintenance and I only top off and don’t even use a chemical since I know the filtration will remove the chlorine and ammonia added with the top off

That was a good point about morning water changes and lower O2 issues. Also, second water tests to insure water stability. Though I never had trouble with fish and water changes, I always wondered wondered if I should wait longer for the declorinator to work. Is it pretty much an instant chem reaction? The ratio of declorinator is pretty small compared to the amount of water being treated, it's tempting to put in more than whats recommended.

Chlorine can often taste salty. That’s a bad sign. Highly recommend bottled water, or water from a filtered fountain, when traveling. I do some waste water and sanitation related things in my real job. Cory makes a ton of validated points.

Another brilliantly informative video!!

Given how much water treatment we need here in texas, I am terrified of putting any tap water directly in my tanks, as even sitting for a few hours in 5 gallon buckets with treatment can still cause my tank water to become cloudy after a ~30% water change. The minimum treatment time for me is recommended api stress coat/dechlorinator + overnight in 5 gallon buckets. I am jealous of people who can just use pythons. On the plus side I get a workout in when I do water changes. If I ever upgrade to a bigger house, I'm going to take into account having a space for a huge garbage container of water to sit around instead of the buckets in my guest bath tube situation I always have.

This is so satisfying. I had an argument with someone after what we will call a bleach accident. All animals are dead and we need to remove the bleach or chlorine from the water.

They told me absolutely not we need to spend money on lots of jugs of liquid dechlorinator because it's made for aquariums. Told them that was a waste of money and the active ingredient was probably sodium thiosulfate. They decided to spend more money.

[@engelsramirez4886]

What are the consequences of overdosing prime or any similar dechloriner

[@engelsramirez4886]

Tom New when I do water changes I don’t know exactly how many gallons I drained out so can’t never tell how much prime to use

[@AquariumCoop]

Loss of oxygen in the aquarium is the first problem. After that would be whatever the reducer agents do to gills etc. if it was completely harmless we would just ship fish in it. Pratically a little more than necessary shouldn’t be harmful. It’s like saying you can never exercise enough! That is true for 98% of people. However you can expertise too much and develop issues from it.

[@engelsramirez4886]

Aquarium Co-Op I notice my fish always gasping for air after every water change so I always thought the water wasn’t fully cleared of chlorine. Thanks for the knowledge. Feedback: if you keep making your videos as short as this one I’ll watch them more regularly 👍

That goldfish tank looks amazing. I appreciate the advice, particularly pertaining to oxygen levels during water changes.

[@kristenwinter8157]

I always run an air stone as I’m changing my water.

[@stephenjakubowski7099]

That only works for chlorine, if your water is treated with chloramine the air stone does nothing. Chloramine is chlorine bonded with ammonia; this creates a more stable and longer lasting disinfectant. And one that does not easily gass off. I'd recommend checking your water provider's water quality report to verify the type of disinfectant used.

[@chrisi4536]

You could use a Brita water filter (or like it) because it removes chlorine or chloramine. The downside you lower pH and minerals related to hardness mainly KH degrees.

[@GooGlyCHieF]

@@stephenjakubowski7099 fairly sure she uses one to help alleviate the oxygen drop, water conditioners are a reducing agent afterall.

[@ericandersen612]

Thank you for the great tips, and reminders to test our water. I do agree that the longer I am in the hobby the more I think I know and barely ever test water. To combat the potential drops in oxygen levels I always hang the hose above the water level so it splashes when the new water goes in, to oxygenate the water a little extra.

[@timp8291]

We absolutely need dechlorinators in my city. When I started back up with the hobby after a 16 year break, I was losing fish left and right, my cycle kept crashing, etc. Turns out from the last tim I kept aquariums, the city has added ridiculous amounts of chlorine to our water supply. I have not lost a fish, nor had a cycle crash since using Prime during water changes.

[@varanidguy]

Safe is so efficient and cheap I'm surprised Seachem sells it lol. I use dechlorinator as a precautionary thing, all of my tanks get 50% weekly changes out of habit.

[@rickywoods3101]

Seachem prime is amazing also. Seriously can't find anything that detoxifies ammonia and nitrite better than seachem

[@JohnT2088]

Ricky Woods but why buy the prime when its more expensive than the seachem safe powder version? Way much more since its a powder version. Save much more money than using the seachem prime. I notice they do not sale seachem safe much in fish store probably cause if not making much money cause they last years if you have a small tank.

@@JohnT2088 ill look into it .. I herd of it before but didn't know it detoxified ammonia and nitrite . I look into it

[@Quiche_on_the_floor]

@@JohnT2088 here's why. You can easily overdose safe because of its concentration. For small tanks (sub 200litre) it's VERY difficult to dose. Apart from that it's brilliant, yes. Source: I work in retail and sell both prime and safe.

[@JohnT2088]

Ricky Woods its the same thing as prime but way more concentrated but in a powder form. A small teaspoon can cover 50-100 gallon of water. So if you have many tanks its way more efficient. People say its very easy to overdose lol. I have many 10 gallon tanks i just do half a teaspoon even without measuring. A half teaspoon can dose 50 gallon of water estimate since i dont have the information with me but i don’t really measure at all. You can overdose it but its very hard unless your a dumbass putting so many teaspoon in

[@v_the_engineer]

I remember watching this video months ago and it stuck in my brain somewhere. Today, I woke up and my fish were gasping at the top of the aquarium. The night before I did a 50% water change. I knew that the chlorine in my water had recently increased in my local area, and so I increased the dechlorinator used. Luckily, my ammonia level was still at zero with both test strips and Master testing kit, just high nitrite (not nitrate). The last few months, I’ve had almost no nitrite. Thank God I came back to this video and verified my suspicion of what happened! This is why I love aquarium co-op!!! Did another massive water change, oxygenated the water like crazy (yes I had an air stone running 24 seven and it didn’t help the situation). Now I just have to check up on it every couple hours. Hopefully it’ll work out

[@v_the_engineer]

Update- didn’t lose a single fish, slowly rebuilding a strong nitrogen cycle. Will probably lose my massive plants but that’s ok. Thanks again Aquarium Co-Op!

[@nancyware7282]

Curve ball! When it rains (or snows), a lot of municipalities add extra chlorine to the water to make up for it. One place I lived, the water was so hard it left mineral rings when it evaporated, and had a constant chlorine smell and taste on a good day. Add in the extra due to weather and, yeah, I should have bought stock in Britta. Come water change time, I ran it through the Britta, added the dechlor, AND let it stand for 24 hours before adding it to the tank. Fortunately I was only keeping two ten gallon tanks, otherwise it would have been impossible to prepare enough water. (I also ran my cat's water through the Britta, otherwise, he wouldn't drink it.) Questions to the water board about the taste/smell of the water were met with the old "we adhere to the standards" line. I'm so glad I was finally able to move away from there.
