Active Aqua Submersible Water Pump, 160 GPH

Reliable Circulation for 15-Gallon Reservoirs

A reservoir only stays healthy if the solution inside it keeps moving, and a pump that's underpowered, leaky, or noisy turns a simple circulation task into a daily annoyance. The Active Aqua Submersible Water Pump uses mag-drive construction to run quietly below the waterline, with a removable foam filter and rubber feet that keep debris out and vibration down across a range of GPH ratings sized to specific reservoir volumes.

The Active Aqua Submersible Water Pump moves 160 gallons per hour at 9.5 watts, sized to keep a roughly 15-gallon reservoir circulating evenly without straining the motor or running up your power bill.

Key Features & Benefits

• 160 GPH output — matches 15-gallon reservoirs, giving the system enough flow to keep nutrient solution circulating on schedule.
• 9.5W mag-drive motor — runs efficiently below the waterline without the oil or seals that ordinary pumps depend on.
• Steel shaft — suited to standard freshwater nutrient solutions.
• Removable foam filter — keeps debris out of the impeller and simplifies cleaning.
• 6-foot power cord — gives flexible placement options within the reservoir.

Who Should Use This Pump

Growers running a reservoir at roughly this pump's rated gallon size, who want quiet, reliable circulation without oversizing or undersizing the pump, are the fit for this model.

About Active Aqua

Active Aqua's submersible pump lineup, distributed through Hydrofarm, spans this GPH-rated reservoir pump series alongside the brand's higher-capacity utility pump and matched replacement impellers.

Frequently Asked Questions

What reservoir size does the 160 GPH pump fit?

It's sized for roughly 15-gallon reservoirs. Going well beyond that size means the pump may not circulate the full volume on a reasonable schedule, and a much smaller reservoir doesn't need this much flow.

How does mag-drive construction help?

Mag-drive motors run without the oil or mechanical seals that ordinary pumps depend on, which is what lets them run quietly and reliably below the waterline for extended periods. That design is also why mag-drive pumps hold up well to continuous submerged operation.

Is the steel shaft a concern for my nutrient solution?

No — the steel shaft is suited to standard freshwater nutrient solutions typical of most hydroponic setups. Match your solution's mineral content against the shaft material if you're running an unusually aggressive nutrient mix.

How do I clean the pump?

Remove the foam filter and rinse it separately from the pump housing, since sediment collects there first. The removable filter design means routine cleaning doesn't require disassembling the pump itself.

How long is the power cord?

It ships with a 6-foot power cord, giving flexible placement options within the reservoir. Measure the distance from your reservoir to the nearest outlet before finalizing pump placement.
