LFS suggested a Tom aqautics sump with a built in skimmer (Rapids Pro PS3) Has anyone heard of these or used one? I was thinking of getting a CPR CY192 but this is nearly half the price (which already worries me) I have a 38g tank - FOWLR - but about to start doing some corals so I wanted to finish getting all the equipment that I will need. Have a Prizm skimmer right now but not real impresed with it.
