When a media reactor's feed pump wears out, replacing the whole reactor over one worn part rarely makes sense. The Reef Octopus OTP 300 Water Pump is the direct OEM replacement pump for the MF300B Complete Media Reactor.
Why Replace Just the Pump
A media reactor's housing, plumbing, and media chamber typically outlast the small feed pump driving water through it. The OTP 300 restores your MF300B to full working order without the cost of a full reactor replacement.
What It's For
- Direct OEM replacement specifically for the MF300B Complete Media Reactor's worn or failed feed pump.
- Simple, affordable fix compared to replacing the entire reactor unit.
- Straightforward installation using the reactor's existing mounting and plumbing.
Before You Order
- Confirm you have the MF300B specifically — this pump is built for that model's mounting and flow requirements.
- Check for other wear in the reactor housing or media chamber while you have it apart for the pump swap.
