Interesting. I wonder how much it helped though.
I would bet quite a bit. Sorta like a massive root tab, it would contain more unused organic material for the plants to utilize.
I'm really interested to see how it goes for you! I was not brave enough to do a full on Walstad tank, I have a sponge filter, light on a timer, and use some excel in my little nano experiment.
I do like the idea of a self sustaining aquarium with minimal intervention though, neat idea. I wonder how well it would work with a really big tank like a 125 or something more stable like that....
