Fluval CP2 Circulation Pump – Aquarium Powerhead
The Fluval CP2 Circulation Pump is an internal aquarium powerhead designed to add water movement in compatible freshwater and saltwater aquariums. With a listed flow rate of approximately 400 GPH / 1,500 L/h, the CP2 can help improve circulation in small to medium aquarium setups.
Additional water movement can help reduce low-flow areas, move debris toward filtration, and improve surface movement when positioned properly. The Fluval CP2 can be used in community tanks, planted aquariums, cichlid setups, fish-only saltwater systems, and compatible marine aquariums.

Why Use a Circulation Pump?
A circulation pump can help move water through areas that may not receive enough flow from the main filter alone. This can be useful behind rocks, wood, plants, decorations, or other aquascape areas where debris may settle.
Flow needs vary by aquarium. Some fish prefer calmer water, while others tolerate or prefer stronger movement. Always position the pump based on the livestock, aquascape, and filtration needs of the aquarium.
Setup & Maintenance Tips
- Install according to the Fluval manufacturer instructions
- Position the pump so flow does not overly stress fish or plants
- Avoid pointing strong flow directly at slow-moving fish
- Use the adjustable direction to target low-flow areas
- Check placement after feeding to see where debris settles
- Clean the pump intake and impeller during routine maintenance
- Unplug the pump before cleaning or repositioning
Important Flow Note
The Fluval CP2 is a circulation pump, not a return pump or primary filter. It adds water movement but does not replace mechanical, chemical, or biological filtration. Use it alongside properly sized aquarium filtration and regular maintenance.
