I was surfing you tube the other day and watching how people clean their fish tanks with only gravel and fake plants in them...That got me thinking...I have medium sized planted tank, but i'm sure all the fish crap that comes out of fish bums would accumulate the same as graveled tanks would...So would i need to clean my soil, or at least vaccuum it once a while? Or do i leave my shrimpees, otos, and the filter do all the cleaning; and scheduled water changes. < Is this enough to keep my tank life healthy for a long time? What do you guys do on planted-tank maintenance?
