I was wondering how many of you have them? I have a layer of crap on the surface that i would like gone. Also how do you clean them...or even better how do these work? Would you say just scoop the crap off insted?
I did that and it only clears a patch of it. I guess i could point another one up there, I just dont want to take too much flow away fromthe body of the tank.
