Collection: Seatorch Protein Skimmers

A single Seatorch series appears on this page: the Ultra Marine, offered in five sizes of 160IN, 180IN, 200IN, 220IN and 300IN. The figure climbs with the size of the unit and the IN suffix stays the same throughout, which makes the decision here a question of size rather than of type. Those numbers are Seatorch model designations rather than capacity ratings, so weigh them against the specification of the unit instead of reading them as gallons or liters. Bioload drives skimmer sizing further than water volume alone does. Check the space on hand where the unit will sit before choosing between two neighboring sizes.
