I got tired of buying carbon filters so I just kept occasionally rinsing the one I had in a hanging filter so it was pretty much bio-filtration at that point. It kept the water moving and with occasional 10 to 15% water changes it seemed to be fine.Aaand im done cleaning my fish tank. I had to leave some biofilm there for when I get my shrimp. Has anyone here ever done a filter-less tank?
