I decided a while ago that I was tired of having a big bulky wave maker, 3+ power heads in the display tank and numerous extra power cables to deal with under my stand. I've been reading and reading as much as possible on all the types of available and affordable wave maker possiibilities and one thing kept coming to mind. SCWD! Aka "switching current water director". My first 75 gallon I I bought used from a relative years back was plumbed with a pair of the 3/4 scwd's and they never failed. I always liked how the flow from the main pump would change direction and it took the place of at least two power heads. I still regret selling them with that tank but oh well. So anyway I decided to give the new 1" scwd a chance to be plumbed up to my water blaster 10,000 with two 3/4 lock line inlets into my tank, so far so good! I've got my 2,600 pump wide open and its alternating perfectly from each end of my new 75 gallon tank making my corals sway gently. It's even giving me fairly good flow at the sand bed. The best parts though is that it's taken the place of three power heads and a Red Sea wave maker, it doesn't draw any electricity and the newer 1" scwd is completely serviceable through the twist on cap. Is super easy to disassemble and reassemble and literally takes 30 seconds to do. I'll try to post a video or at least some pics tomorrow but its worth looking at on YouTube for anyone interested in a different approach to flow and lowering electrical usage. www.drsfostersmith.com/product/prod_display.cfm?pcatid=10668www.3iqventures.com/ |

Nice, I'm still thinking of pairing it with a jebao wp25 as well but for not having any power heads now its doing great!

What pump are you running for the closed loop?

the only problem with going powerheadless is turnover threw the sump, your skimmer is supposed to have more flow than the return fo it has time to clean the water unless you have one very large skimmer  |

No problem with the skimmer size, I have a super reef octopus 3000 rated for 300 gallons. No closed loop either. Just a water blaster 10,000 main pump rated for 2,600 with two eshopps 1000 overflows paired together into a 2" drain. All on my 75 gallon tank.

Ah I read too quick and it make it sound like you had 2 pumps. Excellent though on being able to hide things. It's why I went the sump route to get rid off all equipment just hanging off the back. 34 turnover rate is just about spot on for me.

The thing about the scwd's is that they turn your main pump into two alternating powerheads.

Its funny cause I saw this in ebay www.ebay.com/itm/221223889892?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 and was thinking of using it in my system then I came across this post. I have 3/4 tubing coming from my return pump. It tee's at the top of the tank and branches to each end. Then another tee to two flexible wave makers each side. So I was thinking of using this in place of the first tee for a little more randomness. How is it working for you. |

It's working well now, I had some sand go up through and jam the internals a few times but they are super easy to take apart and clean.
