hahah thank goodness the feather isnt in the display, I only put it in the hob fuge just to help cycle and get rid of pesky nitrite and nitrate. its starting to send roots through my grate though :O so hopefully i can keep trimming those before the fall off into the tank :P thanks for the advice on cleaning the filter. every three days is that necessary?? I do weekly 25% water change out and I ato with fresh when I can, waiting for the float valvue to get here to make my ATO system.
