I'm torn between gutting the sandbed for Bare bottom, or just keeping the back of the tank clear

I did this before with good results, sandbed in front of tank for looks, and the back was kept clear with a rio 2500

The rio eventually melted, I'm not sure if they still do this, the tank is a 75g, so a rio 2500 would be enough to keep the back of the tank clear

the other option is a closed loop added, with a SCWD and outlets on both ends


thoughts? I'm leaning towards adding a simple closed loop with PVC over the back of the tank, I've got a couple external pumps in the 1200 gph range[/u]

I'd go with a closed loop if you have that option. They just seem like less hassle once you get it installed.

IIRC, the melting RIO problem has been fixed.

I'd go with a closed loop too, but not w/ the SCWD.
They cut down on the flow significantly and require too frequent maintainence. Look at the Oceansmotions units for a variable flow option on a closed-loop.

not an option, that will greatly increase the complexity and I dont want to do that

I installed a sea swirl, the corals did not like the mj1200's + seaswirl

the MJ's are now on a wavemaker behind the rocks, it seems to hav worked as it kicked up all sorts of crap from back there

leaving it like this for now

I've had my jig running for 2 years now. 72 gal tank, I have my return pump (800 GPH @ 4') rigged up with PVC to go down the back, T off then go across the entire back. I use a quiet one 4000 which has a 1" hookup. Take 1" PVC and then drill 64 1/8" holes across the pipes that go in the back to make it gentle flow. Make a 90 degree turn when it gets to the corners so you don't blast the corner of the tank clean and let the critters disturb the silicon seal. I did the first one without the 90 degree on the ends and it left the back corners exposed, eventually developed a slow leak in the seal... I think either a crab or enchant messed with it. Okay so the new one with the turn works awesome. Below are some shots fo the old jig without the 90 degree turn at the ends.

The OM 2 way Squirt is no more complex than a SCWD. :?

You get what you pay for. The SCWD breaks down often, sometimes it dies, and can reduce flow by 40%. The OM does none of that and has great customer support if there are any issues. :D

I've never had any problems with my scwd, I dont know how much it cuts down flow I've never measured

it's a whole lot simpler though, 1 line to pump, 1 line out of pump into tank

the scwd is shoved down in the rocks

cant get simpler than that


I've seen what it takes to plumb a squirt, no thanks, maybe if I was setting up a new tank
