I have a question and need help identifying these little creatures that are everywhere in my reef tank, they look like baby star fish and are small and are all in my rocks
I have a 120 gal Oceanic Reef Tank with 2 built in overflows, a 30 gal sump and my stand is 30" tall,what size return pump is needed to pump the water from my sump back into the tank.
I have a 120 gal fish and reef tank and Iam using 48" T5 ( 8 bulbs x 54 watts ) = 432 watts - it has 4 whites, 4 actinics and 4 lunar lights. That is enough lighting for my 120gal correct, and is the T5 ok.
