    Does stir up quite a controversy though.

    There's another thread on RC as well, comparing Sea-Swirls to SCWDs.

    Basically if you consider the price points of each and the advantages each has, you've gotta compare apples with apples and oranges with oranges.

    General consensus is that Sea-Swirls are over-priced but deliver the flow and that SCWDs are cheap but for a small tank do the job well.

    All in all, my perspective is well known as being an advocate of rotating return apparatus. That SCWD looks neat but lots of folks have a problem with how that puppy looks hanging inside their tank. :guns:

    Can't see the SCWD lasting more than a year or so with all that saltwater stuff clogging it up constantly.

    It's not junk, it's un-assembled DIY!

    Actually, the SCWD doesn't have to be in the tank.... Mine's plumbed into my return from the sump, behind the tank. It has flexible tubing hanging out both exits going to u-tubes in the 2 rear corners of my tank...

    I've had mine since March. It was noisy for the 1st 2 days, but hasn't missed a beat since. It is a great CHEAP solution.


    It makes a MAJOR dent in your flow. It cuts down about 20-30% of the flow. It only has 1/2" ID outputs, which really sucks.

    Because of the loss due to the SCWD, you have to make up for it with a larger pump.... In the end, this is great for smaller applications provided you make up for pressure loss with a larger pump, although I too am a firm believer on rotating returns for random current.

    As for comparing SCWD's to Seaswirls.... Like Van says, it's like comparing apples to oranges... They're 2 completely different beasts.
