Switching Current Water Director (SCWD)
* Produces waves with your existing aquarium pump
* The most energy-efficient aquarium wavemaker available
* Creates bidirectional water movement for your reef aquarium
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. It delivers quiet, smooth operation, and is clog-resistant. Features low back pressure so there’s no strain on your existing water pump, making SCWD the most energy efficient wavemaker available. Use with system pumps from 50-1,400 gph and maximum 5 psi. Completely waterproof; mount internally or externally for a wide variety of configurations. 4-1/2" x 5" x 2-3/4" deep. Uses 3/4" tubing. Use clamps to keep tubing in place (use stainless steel for external locations; plastic for internal).
