Classic 152-S Protein Skimmer

This listing is the Reef Octopus Classic 152-S Protein Skimmer — the same compact in-sump design rated for reef and mixed saltwater tanks up to approximately 150 gallons. A needle-wheel pump produces fine, stable bubbles inside a space-conscious cone body, giving tanks with tighter sump compartments 150-class skimming without the 150-INT's larger footprint. Best for: reef and mixed saltwater tanks up to approximately 150 gallons Setup: in-sump, compact cone footprint Pump: needle-wheel pump, self-priming Maintenance: gate-valve water level adjustment Note: this SKU is also listed separately on our site under a different handle — both list the same physical product. Compatible replacement parts: Classic 152 series pumps and collection cups.
