Water movement - Not regular powerhead

[kimha]

I am looking for a device to create additional water movement inside my tank. I am currently using regular powerheads in my tank, but I saw someone else setup that has a black, retangular looking, with roughly 1 inch round outlet. I think the outlet can rotate but not sure.

Do you know the exact name of this device and where to buy one?

I believe you are describing a SeaSwirl. Basically it is a motorized unit that moves the output nozzle for your return in a 90 degree sweep.

I run 2 of these on each of my tanks connected to the return pump for circulation.

There is also a new device out called Wavy Sea - does what the SS does, but is reported to be more durable.

You can get both from Premium Aqautics on the RC sponsers page.

They are listed on this page:

Do you think those are better than the SCWD? I know they cost a lot more $$$. What size would you recommend for a 90g?

Not sure, I have never tried the SCWD. My understanding of them is they generate a large amount of back pressure so be ready for a larger pressure rated pump or more powerheads. I also don't know if they make a SCWD in 1" input and I believe the 3/4" model is limited to 1400 GPH.

I have just always used the SS. For me it was just easier to split the 1" return line to 2 3/4" SeaSwirls and mount them on top of the tank (acrylic). But that is on a 180 gallon tank.

Thanks, I just cancelled my order for the SCWD. I'll get the SS. Thanks kimha, for starting this thread!

I have a scwd in my 58 with a mag 9 and it seems to work fine. I don't think the pressure loss is that bad. Like 10% Here's a link.

i got a oscillator from ocean current, works great. has been running for about a year with no problems. sho tank in mundelein sells them or you can order from the company and get your choice of outlets. http://www.ocean-currents.com/products.html

You can also mount powerheads onto the sea-swirls if you are creative, or on the wavysea which comes with brackets but is pricier.
I got two used SS cheap and mounted Maxijet Stream mods onto them. See www.ostrows.us
