I think you're doing OK, and the advise from Aqua Hero is pretty good. I have sometimes even collected wild bottom dwellers to introduce into deep beds in natural aquariums, but some also came in with plants I collected. Bacteria in the anaerobic layer can help remove nitrate by converting it into nitrogen gas-so some bubbles aren't a bad thing. But plant roots will do a lot to help aerate and absorb nutrients.
