The SCWD is a revolutionary device designed to provide alternating currents without the use of electricty.
The SCWD mounts inline with 3/4" tubing, the two ports alternate the output, the bottom port is the input.
The SCWD will run on any pump with a minimum output of 50 GPH and a maximum output of 1400 GPH. The switching speed and current duration is dependent on the volume of water flowing through the SCWD.
You can control the duration by controlling the flow going through the unit. Can be submersed for use with large power heads or used externally.

Good as described Review by Mbaker
Torn with this device, it works as describe and varies the flow. The loss of power is dramatic and you need to buy a much larger pump to make up for it, 2 sizes up to see a differences. (Posted on 11/9/2010)
not bad Review by podman1973
Overall not a bad product easy to install not to noisy. the biggest drawback ive found is the loss of power (or GPH) you will get with this thing. If you account for that then for the proce you cant do much better (Posted on 9/8/2010)
