Fluval CP1 Circulation Pump – Aquarium Powerhead
The Fluval CP1 Circulation Pump is an internal aquarium powerhead designed to add water movement in compatible freshwater, marine, and reef aquariums. With a listed flow rate of approximately 250 GPH / 950 L/h, the CP1 can be useful for smaller aquariums that need additional circulation.
Additional water movement can help reduce low-flow areas, move debris toward filtration, and improve surface movement when positioned properly. The Fluval CP1 can be used in nano aquariums, planted tanks, betta setups, shrimp tanks with caution, fish-only saltwater systems, and compatible reef aquariums when the flow is appropriate for the livestock.

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 rockwork, driftwood, decorations, plants, and other aquascape areas where debris may settle.
Flow needs vary by aquarium. Bettas, shrimp, fry, and slow-moving fish may need calmer areas and careful pump placement. Always position the pump based on aquarium size, livestock needs, aquascape layout, and filtration setup.
Setup & Maintenance Tips
- Install according to the Fluval manufacturer instructions
- Position the pump so flow does not overly stress fish, shrimp, plants, or corals
- 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 CP1 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.
Because this pump has a fixed output strength, placement is important in small aquariums. Make sure the flow is appropriate for the fish, shrimp, plants, or corals being kept.
