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).

There are many ways to install you new SCWD. The following instructions reflect the preferred method of installation. In addition, even though your new SCWD is not overly sensitive to the normal particulate and debris found in aquarium systems, to ensure long life, water must be filtered prior to entering the SCWD.
Remember that switching speed and current duration are dependent on the volume of water flowing through the SCWD. Higher volume pumps will naturally cause a quicker switching response than lower volume pumps. By adjusting your inline valve you will be able to regulate both the amount of flow and the switching speed.
Symptom: Switching speed too slow.
Symptom: Switching speed inconsistent.
Symptom: SCWD is noisy or stops abruptly, stops and starts sporadically. Remedy: Foreign debris is lodged in switching mechanism. Flush out unit to dislodge debris. Verify pre-filter is installed and is not clogged or restricting flow.
