What is SCWD?

SCWD is a water switching or current generating device. SCWD switches or alternates water in two or more directions, depending on set up. It is an excellent water current generator for both salt water and fresh water environments, whether tank or pond. SCWD also has garden applications. It may be installed in statuary to create alternating or switching water flow from one spout or outlet to another or create decorative displays in garden ponds. The patent-pending device, which requires no electricity, directs water between two outlet ports at varying intervals. The higher the volume of water flowing through the SCWD, the faster the switching response.

Top aquariums throughout the U.S., such as Atlantis Marine World, Birch Aquarium at Scripps, Monterey Bay Aquarium already have used SCWD.

Why do you need a SCWD?

There is a growing need for affordable wave makers to improve aquarium and pond ecosystems and protect expensive coral, fish and other water life and exotic investments. Most wave makers currently require electricity and are expensive. Until now attempts at inexpensive mechanical options have not been optimally designed or manufactured. Small, compact, inexpensive, and manufactured in the USA, SCWD does not use electricity, generate heat, or clutter your aquarium, pond, or garden environments. Get the clutter out of your aquarium install SCWD on the outside of your tank.

SCWD was subjected to over 53,000 hours of field testing and 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’s increased water currents and oxygenation.

The 1” SCWD from 3iQ Ventures was designed and built to the highest standards of Quality and Reliability.  Designed with large aquarium and pond applications in mind, this device will provide increased water movement at higher volume rates.  With its 1” standard threaded inlet and outlets, the device can be hard plumbed with PVC fittings, or soft plumbed using barbed fittings.  The cap is removable, which allows for easy maintenance.  With the new drive design, the 1” SCWD will run with pump applications from 500 GPH to 3500 GPH.  Besides the obvious physical differences, the design of the 1” SCWD is targeted toward higher water volume output, with a substantially increased switching duration.   A longer interval between switching cycles means better water movement penetration to the extreme areas of larger aquariums, providing your corals, invertebrates, and plants with longer periods of time between shifting currents. 

The 1” SCWD comes preassembled with the standard drive assembly installed.  With its efficient new design, the 1” SCWD allows the hobbyist to switch out drive assemblies and diverters to customize the output flow and switching duration to meet their specific water movement needs. (Additional drive assembly and carrier packages will be available for purchase separately.)
