Hard vs Soft Water and its impact on plant health I'd also be interested in how natural sunlight could work for an aquarium

Hi, I think that 2 experiments are needed for our industry: 1. testing a planted tank with and without an under gravel coil heater to see if the heating technology improves plant growth (originally suggested by Dupla in the 1980s - The Optimum Aquarium) 2. testing light options for a tall tank 60 to 100 cm

No water changes doesn't mean no water changes from day 1 until the end of time. Everyone does water changes to begin with until a balance is found and plants are rooted and the soil has done the initial nutrient leaching (no more melting plants etc.). The experiment becomes all but irrelevant with the current approach, which is a real pity given all the effort put in. You should set two tanks up and run them for 4-6 weeks and this is when the experiment should start. That would be interesting. Positive note: I really do enjoy your channel...just constructive criticism :)

glad to see the series is back. my suggestions: expensive aquarium soil vs organic topsoil w/ sand cap expensive LED's vs discount LED bulbs (same lumens, obviously) clay cat litter vs gravel tissue culture plants vs rockwall plants

If possible, I'd be interested to see if a "siesta" (i.e. a break in the photo period, e.g. 5 hours lights on, 4 hours off, 5 hours on) has an effect on no-added-CO2 tanks, because this is what Walstad recommends in her book :) I'd also love to see what the ADA additives actually do, so that could be even multiple experiments (that is, if you can use just a single additive in isolation?)

Seems like a decent enough first experiment, although one month is just about enough to cover the startup-fase, so maybe another month after that to see how things develop? Another idea: heater and no heater. One is set to 23 degrees (day and night) and the other just fluctuates during the day and night. I like the idea behind these all-in-one tanks, but I must not buy any more tanks before I have all of the current 6 up and running! 😅

Deep subtrate vs low substate? DIY CO2 vs regular CO2 system? One filter vs another type of filter? One light verses another light?

Happy this series is back. I would personally run the experiment for 2-3 months, as it'll take at least a month before the no water changes tank stabilises.

I love that this series is back. Maybe budget name-brand lights vs each other (like chihiros and twinstar) and an amazon find (hygger) as well as higher end lights competing against each other.

Theoretically you only need to do water changes when the nitrates get past a certain level. If you have low bio load that could take a really long time or could never happen because the plants are consuming the nitrates.

Personnaly I would have done the water changes in both tanks during the first month, as it is mandatory with aquasoil, and then no water changes in one of them. I think that nothing good can come with no water changes the first month...

I don't really spend much time on RU-vid but your videos especially the experiment ones are perfect to sit down on a slow weekend morning with a coffee and enjoy

Great experiment! I would like to see a normal gravel or sand substrate with nutri tabs vs a special plant substrate

I would love to see a comparison of proper aquascaping lights and cheap LEDs from the hardware store. For us low budget lurkers out there ;)

What a great way to settle some of these debates. Looking forward to this series!

I think a dirted tank and an aquasoil tank would be cool, and with no co2 injection to see how much co2 a dirted substrate actually creates

Hi, Enjoying your videos. With regard to filter media bags, I have found that Tesco's (England/Ireland) reusable vegetable bags are a great cheap alternative. Very fine mesh which can be used for substrate also

I love this series, it strengthen your knowledge and add to your experience I hope to see aquasoil vs root tabs and sand experience Thanks alot ❤

Hey mate. How about a tank with Seachem excel n another without it.

Brilliant looking forward to the series and results and was nice to see the dooa aquariums in a video 👌

i got one! caridina shrimp with and without co2 in a planted tank! which one breeds more? is there more deaths in one vs the other?

Appreciate your content. I got a tank in a dark start, something I learned from a video yours.

I like comparison experiments! you can learn so much from them. I was thinking that at the end of the month you could leave them set up and then put different clean up crew in each tank. See which ones are better.

_just gonna repeat myself..._ I'd love to see LED floodlight or maybe even PAR30 bulb up for the test!

Not an experiment but can we also get an Amano style Nano tank with Riccia fluitans from his second book?! Basically just Riccia, Rotala, Micranthemum micranthemoides, glossostigma, and one more plant or two of your choice

Very nice ...lets see what happens . 😁 I like those Chihiros lamps too...inexpensive,reliable and powerful. Please add the water perimeters from each during the test (ppm,temp, ph)

Next it could be a side by side: Peroxide vs no peroxide and its affect on algae. or glutaraldehyde and its effect on plants.

How about over filtration vs under/normal filtration. Always been a topic that you can never over filter a tank

A+ before even watching, i love these experiment things. whether it's fast cycling a tank, testing aquasoil, or just anything really. like what about shrimp keeping and if you really need xyz thing to really get them going good. or is it possible to breed neons WITHOUT removing them from the main tank? just fun stuff.

You’ve given us a lot from the plant side of things, I mean aquascaping heavily relies on plants. However, I wouldn’t mind if things took a more “fishy turn” 😂. Maybe more videos spotlighting animals instead of plants in your tanks? Maybe a natural walsted style tank and let the life go crazy? And see where natural equilibrium takes the inhabitants?

Very excited to see these side by side experiments back good on you mj

I want to create a no-filter, no water change tank. I'm intrigued with the substrate method of using aquatic compost/lava rock/crushed root tabs. I've also read that ADA aquasoils/contrasoils break down over time and would require changing or supplementing with root tabs after 1 to 3 years. Wanted to ask, from your experience: which substrate will require the least amount of redosing or additional supplementation? What method do you prefer? Have you tried both?

I would like to see a (small) internal filter vs a somewhat larger eternal canister filter. At the moment have an internal filter but I struggle a lot to have my tank stable

Great to have these back, lovely looking tanks as well. I saw dennerle plant base at my local fish shop, might be worth a side by side. Seemed pretty inexpensive as well

what bout moss experiment having high temp 30+ degrees (tropical country) vs. low temp 20-28

Good experiment idea, though I think you'll need at least 6 months on this one to really show the results.

Hi MJ Aquascaping, I just got a Ziss Co2 generator. Please make another video on the Ziss Co2 generator. I really like this system because it started producing bubbles within 20 seconds. Video idea: Ziss Co2 vs pressurized co2

For the tank with no water charges, I think is a good idea to keep an eye on GH, the soil will absorb it don't think?

Great 😃 work sir 👏

Mischien nog een idee voor een test: “Lean dosing” versus “Estimative index”?

It's a nice video my friend, I enjoy watching your videos.

You should do no water changes with c02 and no water changes with no c02

I have this tank too! Few things you may like to know for future use: 1. You can put the co2 diffuser in the end chamber and the pump pulls it through similar to an inline system. 2. An aquael heater also fits in the end chamber. 3. You can pull the sponge up in chamber 1 to act as a shrimp guard. 4. The pump works with a usb fan speed regulator to adjust the flow, good for if you put one of your beta in the tank. 5. When you do water changes, you can just press some tubing on the outflow and then top up in the end chamber to avoid stiring up the tank. Love the videos btw. Always awesome stuff.

Light intensity vs duration like 6 h high light/ par vs 12 h medium light . Im Qurios how different plants grow and color

Two DOOAs for side by side comparisons, not bad at all.😉 I am excited to see the results of the new experiment season.

Love your videos mark, i have a question, i see that all your aquarium has no surface skimmer, how do you get rid of the oil thingy on top of the water? Or you just ignore them? Is it bad for aquarium?

Water changes. Either Juan Puchades style 10% daily w maintenance. Josh Sim 25% 3x a week w maintenance. Or 50% once a week. Or you could make a more realistic one for most people and do 50% 1x a week versus once every other week

I think no water change is fine if not using tap water.

Ok so i have a 250l comunity planted riverscape its been setup for 5 months now i do a water test once a week just like i do with my 60 l 15 l and 30 l o do a strip test and if those seem scetchy i da a proper water test al i do is top ofs and i think i do 2 water changes a year thats it

Interresting... for me, with tape water, at the beginning, 50% waterchanges every day during a week and then, each two days for 3 times, then, 5 days for two times, then 50% each 7 days. 6 hours of light. No fertilization.

I would have done a dark start then move onto no water changes

Thank you for the great experiment. I'm looking forward to seeing the results. However, I have a concern about water evaporation since both tanks are uncovered. Could this be an issue for the tank without water changes?

I have a question. I have a new tank that I picked up but it has been sitting for a while and I’d like to clean it properly before beginning the project. What can I safely use to clean the glass before beginning?

DIY CO2 but using different carbohydrate sources vs sugar, eg. starches, flour etc complex carbohydrates

MJ I am planning to buy a camera to shoot my tanks..which camera and gear do u use?

Nice dooa tanks.

Following along. I do 20 percent water changes every month. I've been considering stopping water changes and topping off water. And probably just up my filtration.

Filter versus no filter

Love your content, but don't love the music :P When I turn it down enough for it to not bug me, I can't hear your voice, lol. Maybe keep the music but lower the volume of it please?

Glad u r back .............missed you so much

Can you comment on the DOOA Aqua 30 tanks and how you like them.

You should repeat the lean vs EI dosing experiment, multiple experiments are needed to draw any real conclusions. Why dont you compare the 2hr aquarist line of products in identical setups, so Apt 0 vs Apt 3 vs Apt E.

Filter vs No Filter Low Budget Light vs High Light

technically speaking zero water changes is not possible ..as at some point water will evaporate and you need to top off with fresh water

Best series is back

HIYA MJ.... ID REALLY APPRECIATE IF U COULD PLEASE INCLUDE LINKS TO PRODUCTS ETC IN AUSTRALIA!! U SHARE LINKS FOR THE EU & THE US. IT WQOULD BE GREATLY APRECIATED IF U COULD PLEAse INCLUDE LINKS TO AS MANY OF THE PRODUCTS U USE (OR AS CLOSE TO THE EVUIVALENT PLEASE). THANK YOU SO MUCH FOR UR INSPIRATIONAL & INFORMATIVE VIDEOS. I LOOK FORWARD TO WATCHING YOU AGAIN SOON & IF YOU COULD PLS DO A STEP BY STEP OF A HOW TOO GET HEIGHT IN UR TANK WITHOUT NEEDIN TO SPEND ALL UR MONEY ON AQUASOIL PLS? ALSO, WHAT ELSE CAN BE USED ,& HOW TO USE DIY IDEAS TOO GET HEIGHT USING MULTIPLE TYPLE OF INEERT & AQUASIOL, SAND ETC TO GAIN HEIGHT & AREAS TO PLANT IN!! HOPEFULLY I WILL SEE U MENTION AUSTRALIA SOON!!

❤❤❤

Personally I think you have the filtering the wrong way around. Seems more sensible to me to go from course to fine then media then carbon. If you put the fine floss as the first thing the the water hits what is the sponge taking out? Nothing, it's already trapped by the floss.

Very cool

I think we're a little bit lacking in the background😗

👍👍👍😎😎😎

I want to see cats video 😂

Keen as

Do a collab with Father Fish. Your high tech tanks vs his deep substrate tanks. I already know the result, buy I just want you to expose him to his delusional fanboys.

I think you sort of missed the point on this one. If I am doing a tank without water changes, its not going to be a high tech tank with CO2.

Water changes... boo hiss! I hate doing water changes. =p I've got a black water tank that I only did 2 changes on to get rid of algae, but the problem resolved itself within a month & I've had no problems since. I have another tank that I had to do water changes every 3-4 days because the nitrates/ites kept spiking. Turns out the problem was a piece of lava rock with some bad bacteria in it because since it was removed, everything's been stable.
