  • In-sump design rated for tanks up to 150 gallons
  • Low energy consumption compared to older OTP pump designs
  • Easy break-in period — pulling dark skimmate within a week
  • Best value-to-performance ratio in its class

Our Verdicts

NYOS Quantum 120 Protein Skimmer

The NYOS Quantum 120 is the quietest protein skimmer you can buy at any price. If your tank is in a bedroom or living room and noise is a dealbreaker, the Quantum solves it. Performance is solid for tanks up to 130 gallons, and 8W operation means practically zero electricity cost.

Reef Octopus Classic 150-INT Protein Skimmer

The Reef Octopus Classic 150-INT is the most recommended mid-range skimmer in the hobby for good reason. It pulls consistently, breaks in quickly, and doesn't break the bank. If your tank is under 150 gallons and you want set-and-forget skimming, this is the one.
