Scwd wavemaker7/24/2023 ![]() ![]() SCWD switches or alternates water in two or more directions, depending on set up. What is SCWD? SCWD is a water switching or current generating device. The 3/4 inch SCWD is ideal for fish tanks, ponds, aquariums, and any place were steady rerouting of water flows is desired. It is, in fact, the best, most cost effective mechanical current generating device available on the market today. SCWD is clearly the most efficient wave maker available. SCWD is a revolutionary mechanical wave maker, designed and manufactured in the United States by 3iQ, to the highest standards of quality and reliability. SCWD (squid) promises to add life giving alternating currents to saltwater and freshwater aquariums alike, as well as ponds and decorative alternating sprays to garden statuary. example: ex: 5 psi X 2.25 = 11.25 ft After years of research and testing, 3iQ Ventures has unveiled an industry changing wave making product for aquariums, ponds and gardens, called SCWD (Switching Current Water Director). example: 5 psi X 2.31 = 11.55 ft Salt Water Multiply the psi by 2.25 to derive feet. Requires no additional energy Sleek and compact Affordably priced Only 4 1/2 X 5 inches Hermetically sealed Can be mounted externally or internally Flow Efficiency Ratings: Flow into SCWD SCWD Output Efficiency Switching Duration 150 gph 90 gph 60% 22 seconds 180 gph 120 gph 65% 16 seconds 240 gph 180 gph 75% 12 seconds 270 gph 210 gph 80% 10 seconds 330 gph 240 gph 80% 9 seconds 400 gph 360 gph 90% 7 seconds 600 gph 540 gph 90% 5 seconds 720 gph 660 gph 90% 4 seconds Converting psi to feet: Fresh Water Multiply the psi by 2.31 to derive feet. ![]() Features: Tested & approved for use with pump applications not to exceed 1400 GPH and a maximum of 5 psi with a minimum rating of no less than 50 GPH. With its 3/4 inch standard bard inlet and outlets, the device can be easily soft plumbed. Designed with small to medium aquarium and pond applications in mind, this device will provide increased water movement. Plus they're as quiet as your return pump, they don't make noise.3/4 inch SCWD (Switching Current Water Director), 3IQ Ventures The 3/4 inch SCWD from 3iQ Ventures was designed and built to the highest standards of Quality and Reliability. Not for everyone, but i like them & will continue to use. Also, plan on an oversized pump, one drawback is that you lose about 40% output with the SCWD & that's before I reduce down to 1/2". Other than that they work really well & keep extra powerheads out of my display. I also run 1/2" returns & just use reducers as close to rhe return nozzle as i can get, usually a foot or so. Also the 1" gets pretty poor reviews since they changed it so that you can break it down to clean it. A couple things that I've noticed.they need to be cleaned about every 6-8 months, which for me entails soaking in vinegar for about an hour while i do a water change/tank maitenance, then a good rinse. I bought a backup in case I needed to swap out a few years ago & it's still new & will be using it on my new tank & keeping the original as a backup. You have to have 2 returns to alternate the flow, but other than that mine has been going strong. 've been using SCWD's for random flow for 6+ years & am still using my original (used) one. Never tried it myself, but the amount of time it's been around must mean something. This product has been in the aquarium trade since I started in it almost 20 years ago. ![]()
