I have found that a small clay pot filled with a peat / topsoil mix planted with your favorite aquatic plant works wonders for stabilizing small tanks w/ or w/out substrate. Large gravel is used to keep fish from digging out the soil. I have never had any anaerobic problems which I thought would happen. Probably because of the porosity of the clay. The plant grows much better because of the soil and it is approx. 4 inches closer to the surface lighting. You can move the plant when cleaning or to another tank if you want. the water in these tanks is crystal clear. It is also aesthetically pleasing to both fishkeeper and fish. As for floating plants....Java fern is the best lowlight plant I have found for this application.

I have found that when using sponges, I can simply rinse it and squeeze it a few times under running water about 70-80F, and put it back in. I don't loose enough bacteria to matter, and the sponge is ready to go again.
