Classic 1000 HOB Protein Skimmer – Reef Octopus

Product details

The “Classic 1000 HOB Protein Skimmer – Reef Octopus” is a hang-on-back (HOB) protein skimmer built for marine aquariums, designed to help remove dissolved organics and proteins before they break down. By pulling these compounds out of the water column, it supports cleaner, more stable conditions for reef and fish systems—especially in setups where you don’t want to add a sump. The external, space-saving layout is intended for aquarium builds with limited room behind the tank.

Features:

• Hang-on-back (HOB) design for marine tanks—no sump required
• Low-profile body sized for most setups rated up to 130 gallons
• Aquatrance 1000s pinwheel pump for air-water mixing inside the skimmer
• External pump placement helps minimize space needed behind the aquarium
• Designed to reduce heat transfer from the pump to tank water for temperature stability
• Includes an air silencer for quieter operation
• Easy maintenance with quick removal of the Aquatrance 1000s skimmer pump
• Reef tank friendly design to support coral growth and fish health (general use guidance)
