I wount to install a closed loop on my 140 and do away with the power heads.

I need to know what is the recomended GPH for a 140 (well 185gal w/ all 3 tanks)?

And has any got or heard of the SCWD wavemaker by 3iQ- I need to know if this will work on my system.

A SCWD is way too small for that size tank, and they restrict the flow too much anyway. I am setting up a similar sized tank, and when I was designing a closed loop, I was going to use an Ampmaster 3000 on an Oceans Motions 4 way wavemaker. I ended up not going the closed loop route, and instead bought a pair of Tunze streams. Either approach would work well for that size tank.

Dumb question but what are tunze streamers and where can I find them to check them out?

Here's a link to more info:

Basically, they are powerheads on steroids. They have a very broad pattern to their output, instead of just blasting a small powerful stream like most powerheads. You can also hook them up to a special controller that will control them for different wave and tidal patterns. They're pretty amazing - a 6000 stream moves 1800 gph and only uses 15w of power.

I didn't consider them at first because I was on a "no powerheads in the tank" kick. But, for a closed loop, you end up with lots of plumbing in the tank anyway, and it's a lot more work to setup. If the sight of them bothers you, they make decorative rocks to hide them. That's the route I took - once I aquascape the rest of my tank around the Tunze rocks, and coralline grows over them, you won't even know they're there.

Here's a picture of a stream inside a rock (it's the only thing in the tank right now, but you can see how well it could blend in once the aquascaping is done):

Sure, get a 6000 with a single controller for now, and you can always add more later. If you know for sure you are going to add another one later, you might want to get the multicontroller now instead of the single controller.

Did you get your streams yet? I was at Global the other day, and John had a couple 6000 streams and controllers in stock. His prices were the same as what you pay online (no one discounts them - can you say "price fixing").

How do you clean a power head that lives in a rock on the bottom of the tank?

My guess is to make the rock that the powerhead lives in easily accessible so you can take the powerhead out and do the vinegar bath etc. I try to clean my powerheads once a month or so. I cleaned all my powerheads yesterday and in just over a month I had tons of calcium buildup and coralline on them. After a nice long bath in vinegar they all look good as new.

Brandon nailed it. If you look at the more recent pictures of my tank, the Tunze rocks are on top of my aquascaping.
