I was wondering how I would got about potting plants because I want to put some in my 60 gal african tank...I think is would be the best way to have my tank planted since the fish like to move the sand around quite a bit...
Some people on the discus forums use clay pots to put plants in so they can technically still have a bare bottom tank for the discus. Seems to work out fine for them and if the plants are good size it does offer an alternative to the usual planted tank.
I once tried with peat (on the bottom) and flourite (on top) in a clay pot. It worked ok for me but eventually I didn't like the look and took them out.
