Hmm there is two pumps in there. One for skimmer and one out going from sump into tank.
Actually it doesnt move much. I took out bioballs and sponge that used to be in sump and put the chaeto between the plastic separator where the sponge used to be. Its open but not free flowing. I have a flourescent light I bought from Lowes, grow light it was called. I think it is 65000 k. I cant remember much else about it. It hangs by clip from bottom of tank. Appears to be very bright. I see it from the other room. I was worried it wasnt directly hitting it. Do I need a different light? Maybe a power head down there?
