* Produces waves with your existing aquarium pump
* The most energy-efficient aquarium wavemaker available
* Creates bidirectional water movement for your reef aquarium

The most energy efficient wave maker available! SCWD uses your existing pump to create bidirectional water movement in your reef aquarium. Plumbed inline, SCWD directs incoming water to two alternating outputs, switching automatically at a rate depending on incoming pressure. Install the 3/4" SCWD with 3/4" tubing and system pumps with flow rates from 50 to 1,400 gph. Install the NEW 1" SCWD with 1" tubing and pumps with flow rates from 500 to 3,500 gph. Use clamps to keep tubing in place (use stainless steel for external locations; plastic for internal).
