Filterless 7.5 cube?
I've seen filterless bowls etc work, but I'm not sure about a tank as "large" as a 12" cube. I have one set up as a shrimp cube, and I was going to experiment with it. I wanted a clean look, so I had planned to drill the bottom and hide the in/out flow of a canister filter as I've seen done on reef cubes. However it would be much simpler to set up a filterless tank, but I'm not sure it would actually work. I'd plant it pretty heavily, but I'm worried about the combination of heavy planting + low bioload of shimp being workable without a filter.
Has anyone tried this before?
