Active Aqua 24W Submersible Water Pump (370 GPH)

Active Aqua recommends this 370 GPH pump for reservoirs up to 40 gallons. Using it on a significantly larger reservoir will result in inadequate circulation and turnover rates for effective nutrient distribution. For larger systems, step up to a higher GPH model like the Active Aqua 147W Utility Submersible Pump to ensure proper flow across the full reservoir volume.

Yes. This 370 GPH model features a ceramic shaft, which is corrosion-resistant and rated for both fresh and saltwater use. Note that smaller Active Aqua models in the 40–160 GPH range use a steel shaft and are not suitable for saltwater applications — the ceramic shaft is specific to the 250 GPH and larger models in the lineup.

Yes. This pump is inline-use capable, meaning it can be installed outside the reservoir in a plumbing line rather than submerged directly in the solution. This is useful for certain system configurations where space inside the reservoir is limited or where the pump needs to be positioned between components. Multiple hose fittings are included to accommodate different plumbing connection sizes.

The foam filter is removable for cleaning and replacement without tools — regular rinsing during reservoir maintenance keeps it clear of debris and maintains full flow rate. The impeller is also replaceable; the compatible replacement part is AAPWIMP400, available separately. Full disassembly and maintenance instructions are included in the instruction manual linked above.

Yes. The oil-free, BPA-free construction means no risk of chemical leaching into water that contains fish or other aquatic organisms. The ceramic shaft and mag drive design are both free of materials that would compromise water quality in a living aquaponic system under continuous operation.

Yes. The pump is UL-listed and rated for both indoor and outdoor use, making it suitable for greenhouse installations, outdoor reservoir setups, and garden water features in addition to standard indoor grow room applications. Always ensure the power cord and outlet are protected from direct water exposure in outdoor installations.

The pump includes rubber mounting feet specifically designed to dampen vibration transfer to the reservoir or surface it sits on — this is the primary source of audible pump noise in most installations. Ensuring the pump is fully submerged and seated flat on the reservoir floor with all four feet in contact will minimize vibration noise during operation.
