As I add more sps it is time to upgrade my current skimmer that is under performing.(Pro-Clear Impact) It is going in a my sump with a skimmer Compartment of 15" X 12 1/2". I had ordered the Reef Octopus Regal 250 but the footprint is a little large. Thinking about the Regal 250SSS but would like thoughts/input on the best options. The tank is stocked fairly heavy and everything is doing very well for now.
