Try not to impede the flow of the filter too much unless it is oversized for the tank, which a thick sponge can do.Wed, 25 Jun 2008 07:42:55 GMTHaileyhttp://www.aquariumfish.com/aquariumfish/board/Topic149788-31-1.aspxCover the intake tube with a spongeTue, 24 Jun 2008 22:39:06 GMTfilipemhttp://www.aquariumfish.com/aquariumfish/board/Topic149788-31-1.aspxHi everyone, I have a 20 gallon tank cycled and everything, but the filter is one of those that hangs on the back of the tank, and sucks in water through a tube that goes down. I have heard people say to cover the intake, but I'm not quite sure how to do that?</P><P>Or would it be better just to use a sponge filter?Tue, 24 Jun 2008 22:15:54 GMTogum
