The Reef Octopus Octo Pulse 4 steps up to 4,500 GPH max flow while drawing no more than 32 watts, built for larger tanks needing broad, gentle water movement without harsh flow hot spots. It ships with the Multi-Function Controller for pulsing and feed-pause control. Flow: up to 4,500 GPH, 32 watts max power draw Mount: 360° rotating magnetic mount with 25-degree gyrating range Controller included: Multi-Function Controller with 4 preset pulsing patterns, 15/60-minute feed mode, and a 0-10V port for third-party controllers Warranty: 2-year limited warranty The 0-10V port is worth planning around if you're running a system controller — it lets an Apex or Reef Angel take over pulse timing entirely rather than relying on the pump's own preset patterns.Compatible replacement parts: impellers and magnetic mounts for the Octo Pulse 4.
