Collection: Seatorch Protein Skimmers

Seatorch lists a single skimmer series here, the Ultra Marine, in five sizes: 160IN, 180IN, 200IN, 220IN and 300IN. The number rises with the size of the unit and every model carries the same IN suffix, so the choice on this page is one of size rather than of type. Those figures are Seatorch's own model designations rather than a tank capacity, so match them against the specification of the unit instead of reading them as gallons or litres. Skimmer sizing follows the bioload a system actually carries rather than water volume alone. Confirm the space available where the skimmer will sit before settling between two adjacent sizes.
