The Reef Octopus Elite 150-SSS Space Saver Super Cone Skimmer puts the same 150-class DC-controlled skimming into a Space Saver Sump body for tighter compartments. It shares the VarioS-2S variable-speed pump and full controller feature set with the 150-INT — the difference is a narrower footprint built to fit where a standard INT body won't. Bioload capacity: 100 gallons (heavy) to 210 gallons (light), excluding sump Pump: VarioS-2S variable-speed pinwheel pump, 15-25 watts, 24V Control features: 5-speed memory controller, slow-start ramp, float switch input, feed-pause modes, 0-10V third-party controller input Body: compact Super Cone footprint, twist-and-lift collection cup, vented wedge valve If your sump compartment is too narrow for the standard Elite 150-INT, the SSS body delivers the same 210-gallon-rated capacity and DC control in a smaller physical footprint.Compatible replacement parts: VarioS-2S pump kits and collection cups for the Elite 150 series.
