Undergravel filters perform best when water flow through the gravel bed is consistent and predictable, creating surface agitation for tank oxygenation. Air pumps and airstones can deteriorate or clog. As a result, they become noisy and ineffective...frequently requiring replacement and/or service.
- Unique Mounting System Adjusts to any demand
- Bracket and suction cups expand mounting options
- Adjustable Flow Diffuser and Aeration Valve Deliver ideal surface agitation and oxygenation
Penguin Power Heads deliver constant flow with fully adjustable aeration and increased surface agitation...and they remain silent at all times. The custom air valve regulates air flow, the air filter eliminates noise and dust, and the intake strainer keeps debris from fouling the impeller...that's efficiency.
Strainer Attachment included. Worry-Free, Safety Engineering U/L listed, CSA available. Epoxy-sealed, moisture-proof motor and electrical components ensure safe operation.
