[@seanu4963]

keep it going for a few more months! See what happens long term.

[@heydudetanks6639]

How about a deep dive into the two top, unexpected contenders? Maybe scape two tanks, one with pond soil + aquasoil and another with Fluval and see how they compare to each other and your past history with the Neo stuff. New scapes!

[@gustavogarcia1948]

Keep it going for at least 90 days.

[@christopherrenn8137]

I'd say keep it going a touch longer. I also suggested in another video for a comparison of, still water, moving water (agitated but no added air/co2), normal air agitated and co2 added to see if ambient air will have any effect on plant growth vs not having any at all. C02 and stagnate is control in this test.

[@AquaVo]

I think the test should run at least 3 month. But you should handle each aquarium individual to see if ist possible to get similar results

[@debbiefox6846]

Many of us use fluval stratum for above ground plant medium for starter plants. It works great for Hoyas and really small plants with delicate roots.

[@adamkis9054]

I think would be interesting to go ahead and add co2 in selected top 4 aquarium...

Yup! Maybe redo the root cap one with less of them and add co2.

[@tanyawylie6750]

Please continue with adding co2! Great light+great soil+ co2 = i wanna see these results! Only way to properly gauge, in my opinion! Thanks for this experiment so far!

Such an underrated channel. Usually channels with videos of this level of production have many more subscribers, but I imagine it’s just a matter of time :)

[@FoolyLiving]

Very good info, thank you. I have sand substrate and my tank went through a huge crash or two in the past month. I decided to add some stratum to the tank that has just inert sand. I wish I could replace it all, but I am going to leave the sand and just add stratum to it and let the fish decide what to do with it when they are able to get back into it. Theyve been in a hospital tank since the crash that happened after a water change. My plants have never grown very well, and when they did, I ended up getting staghorn algae. I do water changes 10-25% every week, but my water changes constantly because we get our water trucked in and I have a water softener. I am so annoyed with this situation, but I dont want to give up on fishkeeping. I really don't know what to do at this point. I am still water changing every week without fish in the tank, as it had to go through the nitrogen cycle again after the crash. I probably should have just started all over again. My water comes out at 6.0 or less pH - what can I add to my tank to buffer the pH to stay around 7.0 pH? Eggshells?

[@nxcoco]

Man you have the best channel. Idk why you have so few subscribers for this quality. I love love love that you use scientific method, you get straight to the point with no personality selling and you’re really talented with this hobby. You have to keep this set up going. Add more time then right before worse tank plants get to unsalvageable add co2

[@IndoorEcosystem]

That's a huge amount of growth difference. Perhaps for the next one you could try soil's and us the walstad method.

[@unidaddy]

Keep it going. You have so much experience with all different sorts of aquariums, your opinion on just which substrate might be better in which situation would be very helpful. I’m going to set up two large aquariums in the near future, I’d love to have an idea going in what would be the best substrate for what I want to do. Thanks for your terrific videos!!

[@BrljoMrljo]

Now i know which soil I will buy for my next tank - FluvaL Stratum. I got no idea why i did not see this video before, but I love results with this tank. Awsome colours and health of all plants, almost no issues with algae and fact that lack of CO2 is not making a mess is huge win for me. Thanks for this video. I plan to rescape my tank in ner future, so this will be way to go. Now only design is left to choose and I am not best designer lol.

[@arrowblue3909]

I have been using pond soil from brico for 2 years and my 60 liter Aquarium with no co2 and low dosage of nutrions are really awesome! In my experience it went really well with pond soil.

[@kleetaru929]

i think we should also consider the plants in the middle of each tank getting more light then the ones on the outer side since they have 2 connecting led sides and the others only have 1 side, which could be also a factor of to much light to much algae orso

[@David4js]

Would make the Fluvol even more impressive considering how crystal clear and free from algae it was

[@gabrielalexander3069]

Doesnt make sense actually

[@fisherchi]

I say keep it going for maybe another 2 or 3 months to see how the substrates do over the longer period. Very interesting experiment.

[@lonnieatk9120]

Keep them going. Add 1 or 2 white cloud minnows or similar to each tank and add a little maintenance as you would with your other tanks. Fascinating experiment.

[@DEATHTRUTH]

I think you should start again, but keep the fluval and tropica and put them up against some other brands/mixes. Like a tournament. Like others have mentioned, I think you should try and control the lighting more to make it more consistent across all the tanks. Using black plastic dividers or something.

[@marthanewsome6375]

I used aquasoil and fine round pebble sand. Had to clean the sand a lot though, but it's a dark colour with specks of other lighter colours. Looks like teeny tiny micro pebbles. Has worked fantastic. I cut the plants back weekly. No ferts and no C02 at all. The only issue is diatoms, no algae at all. But it's a shrimp and snail only tank and full of baby shrimp that graze on the diatoms, so guess that's great. It is a deep bed with red scoria at the bottom then the aquasoil and then the sand. I have to say the sand is so much easier to plant in that aquasoil, so glad I did it this way.

[@hojiscott733]

It would be great to see a runoff between the Fluval & the Pond Soil in full Walstad method tanks!

[@whitewolf5886]

i think ill go with pond soil on bottom and fluval on top of it. maybe 1 inch pond soil, and 2 inch fluval. ill pass from a 13gallon tank, upgrade to a 31gallon tank. + So i want to start the best as possible.

[@PaulZyCZ]

The way capped dirt works is the nutrients leaching slowly into the water. Too thin layer of sand (soft gravel) and nutrients cause algae calamity. With recommended 2"/5cm thickness the nutrients seep slowly and the plants need to reach nutrient-rich levels with their roots. So the plants won't grow fast from the start, but over the months that would change. As the experiment goes, I think #4 wasn't capped properly and #6 may see some issues in the 1-2 months, but maybe not. Aquasoil also falls apart after some time. I'd say the best substrate would be thick bed starting with rich soil, thick layer of sand, some aquasoil and thin capping of sand. That is if I were to start a large planted aquarium going for years. For nano-tanks I'd go with pure aquasoil.

[@Consoul909]

your timing couldn't have been more perfect. In the planning process of setting up 2 tanks right now with different requirements, had this exact question, watched part 1 yesterday, and here you are today. Thanks so much!!

[@big21o3]

I think you should keep this going. No need for many major changes just keep it going with water changes and algae growth. I would like to see which substrate “exhausts” the substrate over time

[@legionaquatics]

it would be interesting to see this experiment again with more heavy root feeder like carpeting plants, crypts and swords. also im really surprised the root tabs caused the most nitrate and not number 6.

[@rsousaaquarios]

Eu mantinha a experiência pelo menos mais um mês. Estou realmente surpreso que as abas de raiz causaram mais nitrato e não o número 6. O número 6 é uma excelente surpresa. Abraço desde Portugal!

Nice experiment! I would have added a cryptocoryne in each of the compartments. Just to compare a pure root feeder versus stem plants which receive most of their nutrients from the water instead of the soil.

[@anjumdanielle4764]

Keep it going, at least through the 3 month mark. I think that's a good amount of time to see how it's going to perform longer term. 2 weeks, things are still settling down to an equilibrium. Great info!

[@RafaelSwit]

Brilliant experiment! I really appreciate your methodology 👍 My suggestion for a follow up test: take results from 4, 5, 6, and now run similar setups with base layer of pond soil, but this time 1st capped with inert black gravel / 2nd with smaller amount of pond soil and capped with sand layer 3 times thicker than soil / 3rd keep same as original #6. Maybe you’ll find an even better substrate combo.

[@kylethompson7354]

Keep it going for another month, the fluval stratum is the one I use. Of course it is the most expensive here in the USA

An interesting follow up would be: How would you fix each tank (not changing the substrate) for example: how would you set the light, or dose nutrients, or ad co2, etc… to make each substrate work?

[@natmontag44]

I think it would be great to try this with RO water or distilled. It was great that you tested pH since that will affect certain plant growth too and I'm not sure what you're water is out of the tap. Obviously different aquasoils will lower the pH to differing levels, but it would be interesting to see how much that might have had an effect. Really great video!

[@multipletanksyndrome]

I love these kind of experiments. No other creator is doing it.

[@CarcPazu]

I can't find aquasoil in my area so I used Fluval Stratum and I love it, everything grows very well, even a year and half later. Advice, put on a good 2-3 inches of substrate to let the roots sink in deep.

[@victorsanzblanco5367]

I would like you to keep this experiment running until nutrient deficiencies start appearing in the tanks, this would help to evaluate which one is the best in the long term. Thanks for this experiment and all your videos, really interesting and useful!

I use Fluval for my plant cuttings. When I want to propagate some, I'll keep them in water until I see roots forming. After that, I add 1-2 TBSP. Never had algae issues.

[@QuimiTraderCaio]

I must say man, I trust completely in your reading, incredible results aaaand work!!! Thank you so much for this, you're awesome man

[@ralphpearson5420]

Outstanding video/information. One question though. Is the pond soil a product from a supplier? Or is it actually where you’ve taken a bucket to a pond and got some of the substrate from the bottom of the pond?

[@timomcintosh8997]

Good start and good video. The thing with substrate is that in nature it is stratified and has a complex structure. The other thing is that plant choice is important. #6 did better because the substrate was more complex. Add a little clay to the bottom and some buried rock/gravel (not sand) structure, and it would win by even more and with more types of plants.

[@IMaqua]

Definitely keep it for another few weeks to see one more update.

[@formgeben]

Your guess with the light coloured sand and more algae makes so much sense. So obvious that I never thought about that context 😀

[@ralf716]

Yes, thats a huge drawback for me, since i love using sand on top.

[@vidmusic88]

Nice video and good to see different soils and substrates work differently for a low tech setup. My guess would be due to the high ph in your water that was always lowered by your co2 usage in your other tanks, making it ideal for the plants. The pond soil + aqua soil could’ve better results due to the fact that the ph was lower and is favorable for plant growth.

[@williammcdowell6257]

Hi Mark, all good stuff. Think you are spot on ref. substrate colour and reflected light, once put a mirror on the back of a tank, not a good idea, loads of algae. High Nitrates are blamed consistently for eutrophication of rivers so I am also sure you are right on the issue of Nitrate leaching and spiking the water column. The Phosphate readings surprise me as well. Iron is hard to measure and it contributes to a healthy green in plants, not as simple as red iron = red plants as some think. Red plants tend to like low Nitrate levels and softer water - not just more acidic water. The water softening effect from the most effective substrate mix also needs to be factored in, especially for the unlocking of limited dissolved CO2. All not easy to do. Thanks again, but, I'm too old to think about a PhD in chemistry!

[@Trains-With-Shane]

This substrate head-to-head test was EXTREMELY helpful. Something I think I might want to see is a reset. clean them all out, re-soil, and re-plant with new plants. And this time add some fish, shrimp, or something to put a small bio load on the tanks. Fish will also introduce a small level of CO2 as well I think. This may change results somewhat. Also less of those nutrient additives in tank 5. So far i'm excited about how well the Fluval Strata did as that is probably the easiest to find in my area.

[@TheMAU5SoundsLikThis]

Epic video! Going to be adding some multipurpose compost to a tank and adding plants. Going to top it off with gravel, cheap stuff from the garden store, and cap with some decorative sand. Hopefully the plants will grow well and then I can add some livestock when the nitrates calm down.

[@Taryn.aquascaper]

Please keep this experiment going. It’s extremely helpful. I noticed when I was doing aqua soil mix with pond soil eventually all my aquariums pH level shot up to 8.4, even ones that I was using distilled water in. I reset all but one with just aqua soil it’s actually the flu Stratham, the pH is staying low and not shooting up. I’m curious to see results of all of these different substrates.

Very helpful test, I am looking to start a 10 gallon moderate to heavy planted.Looking to do low tech, so I think Fluval Stratum will be the way to go.This was a great help in seeing different setups and the results from each.

[@Chinesetakeout382]

I personally use stratum with a thin layer of gravel and sand to keep the tank looking bright. Stratum is also just incredible for terrestrial plant. I use a bit of it in all my terrariums and vivarium.

[@stardust9072]

Fluval stratum is good, I'm using it but the soil is quite light. Hard to plant if you shallow plant. Need to put more soil so you can push it in further.

[@varanidguy]

I think tank # 6 would be perfect for people who want to submit their tanks for competition. You can get insane and healthy plant growth really quick, but that also would lend itself to higher maintenance. # 1 I think would be ideal for the more permanent tank in your living room as it can grow plants well, clearly, but it's not going to give insane explosive growth and cause a big chore every weekend.

[@joesmith9103]

Perfect opportunity to continue your algea experiments!

[@alexanderpopov3587]

Appreciate all the effort and the scientific unbiased approach to the tests! As a next step you may compare Aquasoil and Fluval with different amount of light and CO2. Thank you for the great content!

[@don5i]

Tank #6 seems like a clear winner. Not sure why MJ was reluctant to declare that. I am also wondering what was more beneficial in Tank #6 since the other tank with same pond soil kinda failed. Was it the aquasoil that worked the best or because it was combined with aquasoil? What were the ingredients in each substrate? Looks like Fluval stratum has higher iron (hence the bright red)

[@PaulZyCZ]

It also depends on nutrients leaching from the pond soil and how well the upper layer capped it. I think with #4 the nurtrients were leaching too much and with #6 pond soil nutrients didn't saturate aquasoil that much yet. Frankly I have no idea, if that changes in 2-3 months or later after the aquasoil falls apart.

[@MimicNature]

Great experiment. Thanks for doing this. I do want to point out that there is a variable for which you didn't account. The middle chambers are getting more light than the side chambers. They get direct light from above and some from the lights above both chambers beside them while the side chambers only get light from above and one side. It is interesting that despite this, you still got the best growth in a side chamber.

[@EriksWorld14]

The reason tank #6 is doing so well is the decomposition of the pond soil is releasing CO2 - thus it's maximizing the efficacy of the aquasoil cap and its own nutrients. It's basically injecting itself with CO2. Also the high cation exchange capacity of the aquasoil is going to work well to stabilize (almost like it's storing) the excess release of nutrients being released by the pond soil as it decomposes. This experiment turned out exactly like I thought it would but I'm super happy to see it being validated.

[@EriksWorld14]

And the results are even more telling considering that the pond soil you used isn't all that impressive on it's own - if you sourced a better potting soil mixture and then used another aquasoil or volcanic/clay derivative with a high CAC you will see even better results. This I think is the secret behind not needing to dose liquid ferts and increasing the longevity of some aquasoils since they eventually lose their effectiveness after a year or so.

[@cjday573]

Something I would want to experiment with is the comparison between gravel + pond soil, sand + pond soil, aquasoil + pond soil, and high CEC cap (such as SafeTSorb, montomorillite clay, etc) + pond soil, to figure out whether it's actually the CEC capacity or something else inherent to the aquasoil, because the pond soil alone should have plenty of CEC capacity as organic substrates rank among the highest in that regard. Additionally, one could try this with mineralized topsoil.

[@FG-hw5ep]

I have a low tech tank so the information regarding fluval stratum was very helpful. Thanks!

[@marksmith566]

This is genuinely a great experiment, keep this one going and add a couple of snails, shrimp and micro fish like Chilli Rasbora. You shouldn’t need a filter with all those plants and low bio load 👍

[@mokko759]

Going by these results, I like the Fluval Stratum results best. That ludwigia is just poppin'! The plants looked bushier instead of leggy like some of the other tanks and it appears to be more of a sustained growth, instead of a growth spurt. For a beginner/low-tech tanks as well as for the price ( Stratum is more easily found and is less expensive than some other brands), I would say the Fluval Stratum had the best overall results.

[@theaussiemachine9181]

Its always great to experiment. Maybe try again but with some different substrate brands like UNS controsoil and ada amazonia

[@Jon_Again]

I agree, I think it would be great to see UNS controsoil vs Ada vs Fluval. And maybe after a few weeks start with your DIY co2 injection.

Thank you. Very interesting. My two thoughts: A) What do you mean by "pond soil?" Actual dirt from outdoor pond? And 2) Fluval is popular in US for sure but there is also an undercurrent of disrespect that serious hobbyists have for Fluval, which makes your findings a bit of a surprise.

2 looked the best in terms of color, which makes sense as the nitrates were low and the ludwigia was much more vibrant. But 6 was interesting because the myriophyllum took off, probably due to the amount of nitrates/ammonia in the soil.

[@Luciferkrist]

Going to have to agree with you on the root tabs. Only using 2 would have probably had better results in the gravel compartment, as it was probably too many nutrients for all those plants to handle.

[@MasterDeks]

This was a great experiment and very useful for us fellow aquascapers. My assessment of the results for Tank 6 is that the combination of both pond soil and aquasoil without the gravel cap meant an excess of all necessary nutrients were distributed through the tank in a balanced way, resulting in what I can only describe as an EI (Estimative Index) Substrate solution. In contrast, the tanks with just aquasoil would have been lacking in some nutrients so the balance was off and for the gravel capped tanks, the combination of high light and white gravel in addition to the aquasoil/pond soil being capped prevented enough nutrients from leeching into the water column, forcing the developing roots to the the most work for nutrient uptake. I'd like to see you take the results of this experiment to a bigger scale. How would the substrate setup for Tank 6 cope on a larger scale with CO2 injection? This would be interesting to see.

I say keep it going, so we can have results in a couple of months and see if things remain the same. I'm based in Canada and use Fluval Stratum with Seachem Flourite in 2 tanks (10, 5G). I have good, stable results with water parameters and plant growth. I don't use Co2. In my 1st aquascape tank (15G), I used a (too) thick layer of Fluval Stratum and capped it with natural colored sand and have a permanent issue with diatoms. It's under control because I have 2 nerite snails, 3 otocinclus and a 4 large amano shrimps (+ 2 juveniles, the otos had babies!!) It's not happening in my other 2 nano tanks. One thing to consider with Fluval Stratum is if you have soft water like I do, you'll get quite brutal pH swings, I'm talking 1 full point within a few hours. I had issues with this in the beginning because my tap water reads 1KH, 4GH and pH7. My tank would drop from pH7 to 6 in a matter of hours after a water change, it was absolutely crazy. I have to add crushed coral to my tanks for a couple of weeks. My pH doesn't go higher than 7.5 but I usually remove the crushed coral once it hits that mark and let the water slowy return to 6.8-7. I check my pH like a hawk with a pH pen, the colors are also very close together in the API master kit and I find they're hard to read.
