    It really confuses me how a heavily fed and stocked tank can be do clean. My twenty gallon has who knows how many Guppies and Assassin Snails. It is heavily planted. A few years back it had 40 plus nitrates. Now it has barely any. I guess the Guppy Grass could have done that?

    It would take a lot of guppy grass but it's possible. Some of my guppy tanks are heavily stocked and nitrates stay under control with smallish WCs. I do larger WCs anyway but nitrates stay low between changes.

    Top picture no, bottom picture maybe. The extremely fast growing water column feeders pull far more nitrates out.

    It's surprising how much difference plants make. My 330gal had over 20 American cichlids and 10+ BN plecos and various other fish and I had times where I had to go 3 months with out a decent water change due to heavy work schedule and my nitrates never went above 10ppm and that was with a decent live/frozen diet

    Thank you, I have heard that semi aquatic plants remove more nutrients?

    Of course they did. Plants will eat ammonia over nitrate. Because of this not a lot of ammonia gets converted into nitrate. That is your case. Not a lot of ammonia converted into nitrate and the few that did convert into nitrate was quickly taken care of. I have no experience with guppy grass but IME hornwort is better than beneficial bacteria lol.

    I am just surprised that with that many Guppies, Snails, and very heavy feeding. I prefer Guppy Grass. Another cool thing about Guppy Grass is that a lot of micro organisms grow on it and provide food.

    Hornwort is almost the same as guppy grass, also grows infusoria. The Pothos probably helped a lot too. Pretty cool! I would love to see the Pothos root system lol.

    I intend to test that theory in two similarly stocked tanks very soon. I would say hornwort foliage is roughly two times as dense as GP, perhaps more. But GP definitely grows a bit faster in stem length.

    I have heard that hornwort sheds its leaves.

    Only when it isn't happy. If it is getting decent light and a bit of nutrients it grows stupid fast and dense. I have the shedding leaves problem with anacharis in a low tech tank. All these weeds will take over a tank if you feed them a little. Overstocking a tank feeds them if you don't go crazy with WCs.

    I tend to do fifty percent water changes weekly. Do you think the mangroves are a big part?

    I have no experience with mangroves and don't know how much nitrate they consume.

    Okay, I am surprised my system worked. I always thought of it as more decoration.

    I'd plant oak trees in my tank if I thought it would work. Natural nitrate removal is a wonderful thing :)

    It is, I have heard some people use willow trees. I feel super guilty if I don't do water changes. I skipped a few recently because I was in the hospital. I missed them and phones aren't allowed.
