Doing a little maintenance with a diatom filter. Sucking out some Cyano and general tidying up. Using a reverse UG filter requires that I do this occasionally so nothing clogs. This is the beginning. In a minute or two, you can't see anything in the tank but the copperband loves it and looks forward to this.

I don't know how people run tanks without a diatom filter. It boggles my mind and it doesn't take much to boggle it. :cool:
