Active Aqua Air Pump, 8 Outlets, 12W, 25 L/min

Multi-Outlet Aeration Pump, 8 Outlets

Dissolved oxygen in a reservoir or bucket drops fast once a crop's root mass fills the space, and an undersized or noisy air pump either can't keep pace with the load or becomes an unwanted background hum in a shared space. Active Aqua Air Pumps use a quiet multi-level muffler and an adjustable diaphragm across a range of outlet counts and flow rates, so growers can match pump size to reservoir count rather than running one oversized pump for a single bucket.

At 25 L/min and 12W, this 8-outlet pump is sized for a reservoir, bucket, or small group of air stones.

Key Features & Benefits

• Quiet multi-level muffler — reduces operating noise compared to an unmuffled diaphragm pump.
• Adjustable diaphragm — lets output be tuned rather than running at a single fixed rate.
• Sized outlet count — matches the number of lines you're running without unused capacity.
• Rated flow and wattage — lets you match pump output to your reservoir or bucket count precisely.

Who Should Use This Air Pump

Growers aerating a reservoir, bucket, or small group of air stones — sized to their exact outlet count rather than an oversized or undersized pump — are the fit for this line.

About Active Aqua

Active Aqua's aeration lineup, part of the catalog Hydrofarm distributes, runs from this single-diaphragm air pump line up through the brand's manifolds and dual-diaphragm models.

Frequently Asked Questions

How much air does the 8-outlet model move?

This model puts out 25 L/min at 12W across 8 outlets. That's the combined output split across every outlet, not the rate per individual line.

How loud is it running?

It uses a quiet multi-level muffler, which cuts operating noise compared to an unmuffled diaphragm pump of similar output. It's still an air pump, so expect some audible hum, just less than a comparable unmuffled unit.

What is the diaphragm adjustment for?

The adjustable diaphragm lets you tune output rather than being locked to a single fixed rate. That's useful when you want to run the pump below its maximum rated output for a lighter aeration load.

Is this pump sized for a single reservoir use?

Yes, this 8-outlet model is sized for a reservoir, bucket, or small group of air stones. Choosing a pump with more outlets than you need wastes capacity, and choosing one with fewer than you need leaves some lines underaerated.

Can I run all outlets at different rates?

No, this pump's diaphragm adjustment controls overall output rather than each outlet independently. If you need different flow rates per line, that's typically handled with valves or restrictors downstream of the pump rather than at the pump itself.
