Have this skimmer gathering dust. Bought it for another tank that I never set up. Look at review s on reefcentral or on here. Great skimmer...pretty much a clone of bubble magus/ SWC...all these clowns copy each others designs.Supposedly rated up to 150 gallons, but 100 gallons is a more realistic rating for a fully stocked reef. This one uses an atman/aqua bee pump. $100
