Active Aqua Air Pump, 8 Outlets, 12W, 25 L/min (400 GPH) - Adjustable Output

Active Aqua 8 Outlet Air Pump for Multi-Site Systems

Eight outlets on this pump feed eight air lines from a single plug. Total output is 25 liters per minute, about 400 gallons per hour of air. It runs on 12 watts and pulls 0.1 amps from a standard 120V outlet. A synthetic rubber diaphragm keeps the airflow consistent through long, continuous run times. A pressure dial on the housing adjusts output for shallow trays or deep tanks. Rated pressure is above 2.4 psi. The multi-level muffler holds noise to a maximum of 45 dB. A 4 ft cord reaches a nearby outlet from a shelf or bench. The pump is ETL registered under number 4006823. An intake filter on the underside keeps dust and hair away from the diaphragm. Each outlet accepts standard air tubing leading to its own stone. Hydrofarm covers the pump with a one-year warranty.

Aerating Large Systems with a Reservoir Air Pump

Eight lines suit a recirculating DWC system with several sites, a large reservoir, or a row of buckets. A single big reservoir can take several stones spread evenly across the bottom. Mount the pump on a stable, dry surface that sits higher than the water line. Placing it below the water lets solution flow back down the tubing and into the pump. Keep water away from the unit, and never submerge it. Give it open air on all sides so the motor does not overheat. Run 1/4 in tubing from each outlet to a stone placed at the bottom of the water. Even bubble streams across the reservoir prevent dead zones where oxygen drops. Start at full output and dial back if splashing or foaming becomes a problem. Plastic tees can join two outlets to drive one larger stone harder. In a cloner or bubbler, several outlets keep the stem area fizzing around the clock. Every month or two, flip the pump and clear the intake filter of debris. Swap out air stones as they clog and the bubbles turn large and irregular.
