Welcome to the beautiful world of Aquascaping. To the Green Aqua Gallery in Budapest, on this sunny, Tuesday afternoon. I’m supposed to tell you that this aquarium has overgrown a lot… …Because we were waiting for you Guys, to see how it’s trimmed properly. The truth is that we were so busy with all kinds of video broadcasts here on Youtube, that we neglected it. Enormously. So as in our previous episodes, today I’m gonna show you what kind of technology we used, in order to build this aquarium. I’m also going to talk about the plants, and the fish, and shrimp that are living in this beautiful underwater world. This aquarium is a 650 liter tank. It’s a standard 180P aquarium. Which means that it is 180x60x60 centimeters. And it has been… The whole layout has been inspired by Mr. Takashi Amano. Who built a beautiful tank in Niigata, in the ADA Gallery in Niigata. Many years ago. Me and my business partner Viktor had visited the ADA Gallery in Japan and we saw that tank. That’s a really beautiful tank, you can see it on the picture now. And that was one of the last works of Mr. Amano. Actually not the last one! Because the last one was this one. The Florestas Submersas (Underwater Forest) in Portugal. If you Guys have the opportunity to visit Lisbon, you should definitely stop by and see that beautiful 40-meter-long aquarium built by the Grand Master of Aquascaping, the Inventor of the Moder Aquarium. And that aquarium is a great tribute to him, he died a couple of years ago. The whole hobby remains really sad and empty without him. So the lighting above this tank is… Oh, I looked into it! You shouldn’t look into LED lights. Never do that! Because then you are going to be blinded for a couple of seconds. All right, so 3 ADA Solar RGB-s. As usual. The filtration is… We have 2 filters below this tank. We have the Eheim 2260 which is a Classic Eheim filter. A huge one. You can see it on the picture now. And we used ADA Bio Rio and Seachem Matrix, Purgen in it. This is the main filtration. It’s a huge, 16-liter filter. It has 16 liters of biological filter media in it. On the right side of the cabinet, under the tank… We have another 2273 Eheim external filter. This one has biological filter media in it and some activated carbon. We are using 2 Twinstars in this tank. We’re also using a UV filter to help us with all kinds of floating algae in the tank. UV filters are mainly good for getting rid of the Green Water. If you have Green Water and use a UV filter – you will definitely be able to get rid of that. Similar to other tanks we’re using the Eheim 350 skimmer to clean the surface. This is very important because you need a clean surface ensure that the gas exchange between the air and the water is working properly. If your surface is full all kinds of slime… then you will have an obstructed gas exchange on the surface. That could result in serious algae or CO2 balance problems. We are using a do-it-yourself CO2 reactor underneath this aquarium, with a pressurized CO2 system. We are also using custom-made lily pipes. Glass lily pipes – because the tubing of this filter is bigger than the standard size. The substrate is ADA Aqua Soil Amazonia, the usual Aqua Soil… As well as the ADA La Plata Sand… Which is the decorating sand in the foreground and on the two sides. And obviously we have ADA Power Sand Special M which is helping the plant growth. The base layer substrate is very important. I did not yet talk extensively about the Substrate System in a tank. Basically you have two types of substrate. You have the General Plant Substrate. Which is a clay-based substrate. It’s good for the roots to be in. But you need to have something underneath that. So the substrate system is composed of these two elements. The fertilizing substrate lays on the bottom of tank. The thickness of it depends on how high the General Plant Substrate is. For like 4-5 centimeters of General Plant Substrate it’s enough to have 1 or 1.5 centimeters Base Layer Fertilizing Substrate But for higher substrates you can even have like 20-30-40+ centimeters of this strong soil. That needs to be covered in every aquarium by some kind of General Substrate. We were using the Fuji stones to build this aquarium. Didn’t use any glue to do it. If you want to see how we made this tank you can click below… We have a nice video on YouTube that will show you how set up this aquarium and how we planted it. You will see how many Fuji stones we used in this tank. About the livestock… We have the usual algae-cleaning crew. The Amano shrimp, Otocinclus Affinis, the Siamese Algae Eaters, and the Clithon snails. We also have the Panda Loach, the Corydoras Panda, and the Boesemani rainbow fish and the Puntius Denisonii. So we have 4 types of fish in this tank. We were trying to select bigger fish, because we thought that for this kind of tank… In the 180 centimeters wide tank we would be able to show you a little bit more colorful and bigger sized fish. This fish will probably be too big for a tank 120 centimeters, but here they look good. They have really nice colors and they compensate the layout perfectly. As far as the fertilizing system goes… We are using ADA ferts in this system. We are using the ADA Brighty K, and we are using the ADA Mineral. As well as the Seachem Excel. To help a little bit the tank to fight the algae. We are dosing these through an auto-doser. A GHL computer that Viktor is programming all the time. We can see some pictures of him sitting down here… And programming this GHL Doser. Fact is that you don’t need to program the doser from a computer. You can do it wirelessly. But in order to set it up and have a firmware upgrade you would need a computer. We have a weekly regular water change of 40% on this tank. Being a bigger tank, we don’t need a 50 or 60% water change. At this time. It keeps the tank algae-free. I think I don’t see any algae problems in this tank at all. So it’s time to go to the trimming now! Check it out! This tank is really overgrown. You can see that stem plants have already reached the surface. I would like to keep them at least 5 or 10 centimeters below the surface in the center of this aquarium. All right so I’m going to start the trimming by stopping the filters obviously as last time. Stopping the CO2 as well. Here we go. And then I take my usual tool-set. After stopping the filters I’m gonna go to start to trim the stem plants. I forgot to tell you that these plants are sponsored by Dennerle. Thank you again Dennerle for providing us with these good quality plants. I’m gonna start trimming the Matogrossense and I’m gonna start trimming hard. From the foreground. I don’t really see what I’m doing here at this point, because it is so overgrown. So I’m kind of half-blind while doing it. I’ll start to go one-by-one from the bottom here, where I see the connection with the rocks. I could actually move up from there. I’m going to ask probably Viktor if he has a minute to help me with taking out the remains of the plants. With a fish-net. Because we have so many plants in this aquarium that it’s impossible to trim when they come up to the surface. For those of you who do not know it is very easy to trim these plants because all of them are coming up to the surface. The only exception is the moss. Which needs to be sucked out because otherwise it would float everywhere in the tank. As you can see we are done with first part of trimming the stems, and I have two big holders of remains of plants here, in my hands. Obviously, there are a lot of plants that came out of here. We’re going to use the tops – as I told you earlier – we’re going to use the tops of some plants because they are beautiful red. And I’m going to put them back in. But before I do that I’m going to do a fine-tuning on the trimming itself. Yess! We are done with the trimming. One and a half hours. It’s a little bit more than for a smaller tank because we had to take out a lot of stem-plants. We had to trim, and suck out the water at the same time to get rid of the Weeping moss. That was floating in the water. Obviously this is a bigger tank so it needs a lot of water. 650 liters, and we changed about maybe half of it now. So we changed 50% now. Because of the trimming.

Also, if you have questions and comments, please post them. Down there. Below us. And we will answer any questions that you have, regarding this tank. Or any other tank as matter of fact… Until next time, goodbye.


  1. Stunning!! Love it!! Thank you so much for sharing…. quick question, you used the Eheim surface skimmer but why don't you use the lily pipe inflow that comes with built-in surface skimmer instead?

  2. I like this kind of videos, please more of it!! Amazing quality and content 👍 I am happy to visit your gallery next spring!
    Greets from Bavaria 😃

  3. Hello guys, great video of a stunning tank! I'm really interested in your diy custom co2 reactor… Saw the bottles standing in the cabinet (in the 450 litres also).
    Could you guys show us a bit more of your system and maybe do a video on this topic?
    Keep up the good work, you do amazing things in your shop!
    Greetings from Holland

  4. Link to the DIY co2? Looking for a less expensive option for a new 55gallon setup that I'm about to start. Yes, there are lots of DIY videos out there, however, some of them seem to be unprofessional and may cause more harm than good. You guys seem like you know what youre doing! Beautiful tank; I hope to someday have a house full of masterpieces such as these.

  5. Great work! Do you always use the standard dose of ADA Brighty K and Mineral? Or increasing this up to 1.5- 2 times? Do you even make the ADA fertilizers dosage increase?

  6. It's lovely but a bit heavy and solid looking in the center. Hopefully the added red plants with a variety of texture will break up that solid mass of light green bulk. Thanks for sharing.

  7. Really well done it does look like a similar vision to Amano's tank. I think the fish are an excellent choice too, they really help with the imagery of a serene underwater world.

  8. Uau! There's so much to be said here…

    About de VIDEO:
    So cool! Balazs you're a natural… great presence, great hosting, great rythm, congrats! The editing and the music are to die for! [ I know how much love and work go in to that 😉 ] Overall, just BRUTAL is the word.

    About the TANK:
    Very inspiring and aspirational… the simplicity of plant choice and the flow of it's arrangement, the complementary presence of bigger fish, the architecture of the layout that immediately calls out Sensei Amano's signature, and the quality of general hardscape and all the hardware involved. So, so, up-scale… uau!
    Tonight I'll be dreaming about this one, for sure.
    Thanks for sharing in such detail.

    About our common source of INSPIRATION:
    As a Portuguese, I feel very humbled, blessed and honoured to have Sensei Takashi Amano’s ultimate project – FLORESTAS SUBMERSAS- present in my country’s capital Oceanarium
    It’s always a very fulfilling and inspiring visit, and we locals are most fortunate to have the opportunity to go see it very often
    I DO HOPE that projects similar to this, take shape all over the world!
    And of course that if Budapest ever finds the will and the means to make that happen, I wish you guys could lead such project as ambassadors of our underwater world.
    May you be so fortunate to find a sponsor with the same passion for Aquascaping and Nature Aquariums similar to ours…
    On that journey, I wish you the very best of luck! 🍀

    Absolutely AWSOME guys. Namaste. Peace. 🙏🏼⛩

  9. Love ur videos…. Good learning!!
    I have noticed curling on rotala rotundifolia leaves (the ones on the top). This occurred after a water change.. could it be because of the water falling on the leaves while filling the tank. They still appear curly, even today morning….

  10. loved your way of explanation n your experience…… hang on with you work….. n we r eagerly waiting for you nxt video……….

  11. hello to all the team green aqua
    your channel … my drug 🙂
    your work is precious and stimulates everyone's passion sharing with us congratulation
    I wonder if you follow the redfield ratio in your fertilization ?
    I have in my aquarium a plants growth in slow motion
    I think it's a limiting factor in water chemistry
    what do you think of my settings water ?

    • PH = 6.8
    • GH = 5
    • KH = 4
    • CO2 = 20 ppm (green drop checker)
    • FE = 0.1 ppm
    • MG = 6 ppm
    • K = 15 ppm
    • NO3 = 10 ppm
    • PO4 = 0 ppm

    Should I add PO4? i'm fear that the algae are coming

    Soil: ADA amazonia and additives
    light: 100W Led 7000K (no RGB)
    Aquarium: 100x50x50

    thank you for your vision and your advice soon ^ _ ^

  12. You offer really hig quality content and make me just want to visit Green Aqua! I really enjoy too how you keep Amanos work and phiolosophy living. I am kind of sad to never have met him in person, but as he said – the story will grow inside of you and me. I am absolutely sure it will.

  13. You did a great job of the trimming.
    I enjoyed watching this.
    Thank you for sharing, I left a like.
    The video was very well composed, great content.

  14. Sou português e tenho um aquário do qual gostaria de fazer algo, não muito grande tem de comprimento 90 cm, largura 35 cm, altura 45 cm que conselhos me dá.

  15. beautiful aquarium, like all of your company, are awesome, congratulations for the great work and dedication to planted aquariums. almost esquici and her hair is creeping down. lol

  16. Balazs I am a big fan now! You r one of the most underrated scapers in the world. Your presentation and comic timing is also fantastic! Keep up the absolutely masterclass work and congrats on creating this heaven on Earth for people like us!!

  17. Amano's books are truly amazing. I bought his books years ago.
    Today I am still looking at them with no regrets.

  18. Great job guys! How do you keep the plants so thick and green even several cm below the apical area? When I trim the stem plants I always have the exposed air roots and the leaves that remains thin and tend to yellow.

  19. This is an amazing tank guys. Well done I really like the more nature type aquarium.
    One question on the weeping moss. How do you get yours to look so neat? I had issues with the weeping moss not wanting to cling to the wood.

  20. This is the most beautiful tank I have yet to see 😍. I plan on scaping my 90 p to try to replicate it exactly. What would you recommend for my fertilizer regiment?

  21. This tank is amazing , i have watched this video several times… Does moss cotton works for riccardia chamedryfolia? Does riccardia roots on branches or need a permanent fix like riccia line?

  22. I looked almost all you movies, I really like it but I didnt see any movie for real beginners … I have tons of questions . Do I need RO for aquascaping?
    I would like to start with 90cm aqua , which filter size should I use for 600l?
    Could you make some movie about basics, how to prepare water , do I need to wait with fishes after start of tank, what to measure and how? Etc.etc.
    You are doing great job , I really like your videos


  23. Do I need to turn on oxygen 24*7 ??? My aquarium water temperature stays 24 to 28 degree Celsius

  24. Thank you, beautiful! Can these Nature Aquariums be made so the Lilly pipes, CO2 pipes are not visible? I find all the pipe work distracting to the natural environment / aquascape.

  25. Not gonna lie. I enjoy looking at your version of the scape rather than Amanos. I do love Amano’s work though

  26. Why doesn't the soil "leak" through the rocks? Did you put any artificial barrier behind the rocks or did you manage to close any gaps with the rocks?

  27. Fantastic! Thank you for sharing. I have noticed a definite lack of videos on Youtube that show hobbyist how to trim plants. Please keep 'em coming! -Little Bobby
