I think I may have screwed up on this one. I read somewhere that putting small bits of clay into the bottom of the substrate will help the plants grow much better. Essentially clay is dirt so I thought " Yeah that sounds like it should work." Well I don't think so anymore. Since then all my plants have been slowly deteriorating. Everything but my anubias nana that is. I'm about to tear it down and start over because its just pitiful to say the least. But before I do does anyone have any suggestions as to what I can do? I tried to dig out the clay but its mush and just clouds the tank. Any help is appreciated.
