For sale 1 x tested and working SCWD. I am located in Glendale, CA 91206. I accept Paypal and money orders.

Asking $20 for local pick up, $25 shipped.

I've tested it today and it cycled the water perfectly. I'm including a second one that doesn't work just in case you're interested in repairing it. Pics are below. The one with the rubber band is the one that doesn't cycle the water.

What SCWDs Do

What SCWDs Do

Hello,

They provide alternating currents from one powerhead or return source. They're pretty neat. Here's some detailed info from the Marine Depot website:

http://www.marinedepot.com/md_viewItem.asp?idproduct=3Q1111

The SCWD (pronounced "squid") 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. A great alternative to expensive electronic ball valves. The SCWD will run on any pump with a minimum output of 50 GPH and a maximum output of 1400. 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 SCWD. Can be submersed for use with large power heads or used externally.

SCWD is regarded by industry experts as the most energy efficient wave-making product on the market. It replicates nature by generating alternating currents within a tank or pond. These currents stimulate coral, fish, and plant growth and keep other aquatic life healthy because of the tank or pond痴 increased water currents and oxygenation.
