The IceCap K3-100INT In-Sump Protein Skimmer is the entry point to the K3 in-sump line, built around the DCAIR 1.0 pinwheel pump with 10 adjustable power levels and a feed timer. A submerged, pipeless outlet keeps operation quiet with minimal turbulence. Bioload capacity: 40 gallons (heavy), 65 gallons (medium), 80 gallons (light) Pump: DCAIR 1.0 pinwheel pump, 10 watts, 10 power levels, feed timer Dimensions: 4.7in x 6.3in footprint, 4in body diameter, 19in total height Optimal water depth: 6-8 inches Cup drain: 8mm ID / 12mm OD The 10-level power adjustment is the real advantage over a fixed-speed skimmer — you can dial down output for a lighter bioload or run it harder as the tank matures, all from the same unit.Compatible replacement parts: DCAIR 1.0 pump kits for the K3-100INT.
