Thanks guys for the info, Pat, u speak of sponge's. So r we talking the type one might use for cleaning up ? And can I just add a cut out piece of sponge and add it to the pump on the two smaller 10 gal tanks ? I am now thinking I can add a cut out piece of sponge and add it to the small bowl area in the circulating pump, may not even work but where to add a sponge? And I have no gravel, I do not see where gravel is added to tanks when raising Tp ?
