Reef Octopus NS80 Nano Skimmer

The Reef Octopus NS80 Nano Skimmer packs core protein-skimming features into a small footprint built for nano tanks. It fits small wet/dry sumps, nano tank overflows, and even in-display setups, with a positionable mounting bracket that lets you angle it to fit odd corners. Filtration capacity: 10 gallons (heavy), 15 gallons (medium), 25 gallons (light) Pump: OTP-200s pinwheel pump Features: bubble diffuser, positionable mounting bracket, easy-remove collection cup, adjustable riser pipe for water level control Warranty: 1 year on pump and skimmer body For a tank this small, skimmer choice matters more than people expect — a unit sized for a 10-25 gallon nano tank avoids the over-skimming that strips a small system of trace elements too fast. Compatible replacement parts: OTP-200s pump kits and collection cups for the NS80.
