Heavy fish stock VS no fish stock. How much of a difference does a big bioload do to plant growth?

[@maluskakrecik]

Siesta vs no siesta. (My experience has been that siesta is actually counterproductive despite intuition telling you it's more growing time)

I would love to see a lighting experiment, 9000K vs 2000K.

[@Cooper_2309hhh]

Next experiment- Have one light on for 7 hours straight, while another light has a brake in the middle, so is on for 4 hours with a 3 hour brake then on for another 3 hours. would be interesting to see the results on this. And as always another great video!!

[@rlemburg]

Love to see this run, get a definitive answer on the split light schedule

[@WhatIsMisophonia]

That depends on the soil. In dirted tanks, co2 is created through decomposition in the soil. In aquasoil tanks (especially very lightly stocked tanks), much less decomposition can occur. As a result, most of the co2 comes from air diffusion (or co2 injection) into the water. The middle dark rest period, or "siesta" as Walstad calls it, really only works for dirted tanks because it allows the substrate to replinish the co2 so that the plants can more effectively compete against algae. As a reference, I have a non-dirted heavily planted tank with an UG filter, and the rest period did nothing for my plant growth or algae reduction. Now, I also have a large amount of surface agitation, and surface agitation can release co2 so that it's not allowed to build up any more at night than day, so that could be a confounding factor. In other words, REQUIREMENT: experiment should have minimal surface agitation. Another factor is fish load; If you have a lot of fish, most of your co2 could come from them, day or night.

[@formgeben]

As a newbie I learned so much from your videos already. You have such a calm way explaining everything

[@SyphriX]

You can mix your own ferts for lean as well, and I think that would bring the costs closer together. Also to prevent the mold, you can add 10 milliliters of glutaraldehyde (usually sold as a “liquid carbon” in products like seachem’s excel) to the micro solution. Alternatively, if you store the ferts in a fridge, it will prevent the mold growth as well.

[@philcarlino6942]

Thank you for this advice. Very helpful!

[@pecal1115]

Do we really need to store fert in fridge?

[@peadookie]

I do 20% glut in my micro.mixture and store in the fridge. Never an issue and I dose glut at the same time as ferts (long battle with bba)

[@peadookie]

Also, @Mike Brown - have you mixed for lean before? considering mixing for lean and increasing root tab usage to help with the BBA (using black diamond sand for substrate).

[@chunyonglee531]

Idea for next experiment. plants grown in different rgb colour for example higher blue or higher red colours. Keeping the whites and green as a common variable.

[@nico4xo812]

Thank you very much for this video ! I was on the verge of letting myself be convinced by lean fertilization for my next project, I had almost decided to try this method. And then I know I wouldn't! the compact aspect of the plants is, for me, what makes the difference visually and your video showed me that it is the estimated index that gives that. So once again thank you 🌱🌿💦

[@johnvanderploeg]

Great videos! One important difference you didn’t touch on is the difference in growth form. With EI plants grow much less systematically. You can really see this is the myrio which is growing very nicely in the lean tank and is a tangled mess in the ei tank.

[@dm7797]

My opinion is if your substrate like an aquasoil is already stable or old enough, you can go EI. If new then you go for the lean dosing. Because if rich in nutrients you might see yourself ended in Algae bloom if not proper took care of it.

[@IMaqua]

Next experiment; using LED with different light spectrum 3000k vs 6000k and their influence on plant growth.

[@deShadua]

Thank you, I am doing well, thanks to your channel. You have inspired me to start my own planted tank. I have my own “big shallow” now and it is doing well thanks to your knowledge. Appreciate you and I hope your doing well as well 🙂

[@WhatIsMisophonia]

I know this is several months old, but I just watched it so it's knew to me. Anyway, even though I'm no expert, none of this was surprising to me based on my few years of aquarium keeping so far. If you're doing the same water changes on both, of course you're going to get more growth from the ID method, since it's more broad spectrum and adds more fertilizer in general. Of course the ID method will grow more algae too. And as far a compact growth goes, bear in mind that co2 is a nutrient as well (for the carbon), and plants that have more co2 grow more compact because they don't need to reach and expand out to capture more co2; It makes sense that this is the case with other nutrients as well. As far as cost goes... The average person might think lean would be less expensive, but for that method you're using pre-made liquid fertilizers, which are one of the biggest ripoffs I've ever seen in the aquarium hobby, so of course that would be several times more expensive. Of course you don't need to do buy pre-diluted potassium, but you don't need to do that with the micros either. There are a hundred different aquarium plants, and there's no perfect fertilizer for all of them, considering different plants are going to have different requirements, and aquarists are going to have those plants in different combinations and amounts. As such, I approach planted tanks more with a lean cheap generic broad spectrum fertilization (mostly fish food), plus a boost in NPK here and there, and I don't change water. I have some algae issues, but it's not bad. Personally, I'd love to see some medium to high tech planted tank aquarists come up with methods that don't require water changes (combined with non-ripoff fertilization methods).

[@tobbyland4438]

Hi man😢😢😢, thanks for your attempt. But the experimental conditions were heavily manipulated by taking the self-made, dumped together nutrients from an unknown source. Correctly you should have started everything identically. So you also have to use the same fertilizer from your sponsor and then simply fertilize according to the Estimate Index. Then it would be correct. You don't have to harm your sponsor with it. But as it is, the whole thing has a very strange taste in my eyes for the audience. But the video is in very good quality👍😍

[@klebberbrazilian.theprofessor]

What a GREAT content you put out to us in that video! Thanks a lot! I guess a hybrid approach between those methods is the best thing to do, adjusting accordingly to each tanks features: plant mass, substrate, CO2 etc.

[@almahiislam3424]

Different plants has responded differently 😮.Didn't expected that

[@NohNes]

Great videos on the playlist! Makes decision-making a little easier. Next experiment I would like to see is a comparison between the dark start method and planting and filling from the start. Keep up the great work! Enjoy your channel immensely!

[@padraicbrady]

I'm a week or so out from ending the "dark" period. Tests allowing. I actually rebuilt the hardscape (not soil) after two weeks of watching it which was an unforeseen benefit. First aquascape so mistakes were made and I had time to fix them! I would second that comparison.

[@aquascapeguide]

Love this! We at ASG were super interested in your results. Idea though, is your source of potassium on the lean method is just that, potassium only? If so, couldn't you just use the potassium sulfate from your kit to make your own potassium supliment instead of buying a 100€ bottle of watered down potassium sulfate. In the US we can get a bag of potassium sulfate for a few dollars, and as you calculated it will last years. Also, you can make your own trace elements from CSM+B or something like Microplex. Again, waaaay cheaper to mix your own instead of buying it premixed. We love your videos and what youre doing for the hobby! Keep up the amazing work :)

[@tigersunruss]

Interesting how they say over dosing won't cause algae, yet here we are, algae.

[@aquascapeguide]

@@tigersunruss We really love the EI method and suggest it to our viewer base because of how well it grows plants. When balanced properly you won't get algae. Also, the "EI method" recipe is different in Europe than it is in the states. We suggest Tom Barrs old recipe from 2005. Maybe that has something to do with it.

[@1Venger]

Totally agree liquid fert companies are destroying the world solely for profit, dry ferts are the way forward for this precious world of all of ours.... I use dry ferts in my aquascapes here in Brazil too.... People often fail here because they don't use enough ferts because liquid ferts are way too expensive here... csm+b is amazing and I found a company here in Brazil selling a similar dry micro fert too!

[@1Venger]

@@tigersunruss I guess the ei TANK DIDN'T achieve balance yet?

[@aquascapeguide]

@@1Venger Destroying the world for profit seems a little extreme, lol, but there are more efficient ways to fertilize. That is for sure. When we mentor those starting out, we generally start them on an all in one, and when they get comfortable with that, we move to them to the EI method. With all the science we need to learn in the hobby, its hard to push the EI method onto someone in the begenning. But once someone is ready, its REALLY sustainable, which is great! :)

Thanks for sharing! "Scientifically" it always is important that an experiment can be reproduced. Maybe take the plants where you really saw a difference, maybe even with cut pieces from both tanks, and check, if you will find the same results again in IE vs. lean. Evtl. even leading to solid advices how to fertilize specific plants and how they develop in what environment, respectively...just an idea

[@williamkam4292]

Can you try for the next experiment, a tank with sufficient flow and one with poor flow. I always read about how flow can deter algae issues but I’ve also read about how expensive filters can be overrated.

[@WhatIsMisophonia]

These are separate factors. Not everything that creates flow is a filter. Cheap air/water pumps can be used without filters to create flow, and conversely, filter bacteria can compete with plants for nutrients.

[@Casey_Ezaziel]

As a person who doses dry salts straight into an aquarium with the E.I method. Dry salts also don't spoil like liquids. 10-20 GAL: KNO3 - 1/8 tsp kKH2PO4 - 1/32 tsp K2SO4 - 1/32 tsp MICROS - 1/32 tsp Dosing Micros Monday, Wednesday and Friday The macros on Tuesday, Thursday and Saturday as above. And a 50-70% water change Sunday This method costs me 8c per week per aquarium. And that green spot algae in the EI tank can be fixed by increasing the phosphate kh2po4

[@gaetanp77]

The hell is a 1/32 tsp 😂 USA would literally use anything but SI.

[@williammcdowell6257]

Thanks Mark. Your pre-mix brand is clearly expensive - had you just mixed for lean dosing it would have been very cheap, dry trace micro nutrients and separately, potassium, are available. My only other thought is that EI can be problematic if light, heat or CO2 is not kept constant - using DIY CO2 might not be a good idea long-term with EI. Summer this year was a challenge for all of us in NW Europe, my tank was for several weeks 30 degrees centigrade, way above the optimal 23-24, I had to increase CO2 to help control algae but obviously fish can suffer if oxygen levels fall significantly, a real issue for warmer water. Cheers as always.

It's very interesting to watch, but you should have explained how many nutrients were added, you should have clearly stated in the video how many ppm of nutrients per week you added from each method, not the results from the water test, but from what was added to make it clearer. So how many ppm do you add from each method per week (N,P,K,Fe) does the masterline product contain the ingredients?

[@craigsdifferentvideo]

i think you should do EI but with limited nitrogen. I think you'll get all the benefits of compact healthy growth with limited algae. I enjoyed this video though. I use my own EI solution with no Nitrogen added (fish waste provides this) and for Micro i use Easylife Profito, which is an all in one fertiliser but with no nitrogen or phosphates but mainly trace elements.
