figuring out flow
- Thread starter Pico1

If you must use powerheads....
Put them on the side walls, near the top, facing the center of the tank. The intersecting paths will create random flow in the tank.
Having said that, I think closed loops are a much better way of creating flow in your tank and are much more aesthetically pleasing. Just my 2 cents.

i would place the seaswirl on the right back corner so that the flow goes across the tank and into the overflow to your sump. and go w/ how wombat described for the mj's . i would skip on the hydor flows. the gears in the hydor's will wear out on you in a couple months and stop spinning.
See the arrow under where it says "55 AGA"? I meant put the MJ on that pane (the side wall), facing the same direction as the arrow. What you have there will work, but you're going to be aiming the flow at the front glass, not the corals.
Didn't you say you had two? One MJ 1200 and your return are not nearly enough flow for a 55 g tank. IMHO.

Return pump, Sequence.
As for flow I would do as Matt suggested and have the two MJ at oppostie ends. I would place the seaswirl into the middle back of the tank so it helps randomize flow across the MJ streams. Something like this;

Exactly.

That should be fine. You'll have to tweak the flow some to get it just where you want it, but the more random the better.
Also, on my two Seaswirls I pulled the 90degree elbow off and went with a lockline connection to a flair tip. I can angle this down into the tank rather than having all the flow right in the top 3" or so. If you don't have it at YR you can probably have it ordered from your supplier...or head to Rocklin. The CRS may have some as well, since it's right by your hosue.

Or maybe use a 45 degree elbow? I believe O street carries a limited selection of loc-line too. If not, www.modularhose.com

The overflow can't go in the center because of the center brace. I think I'll get a "Y" fitting for the sea swirl have the bottom output with a flare pointing down and leave the top output be for surface aggitation. I'll have the MJs at oppisite ends, the overflow on the left, and the seaswirl center/right. Sound good? Also sequence pumps are WAY too heavy flow. Its a mixed reef and I only have a few of my favorite sps and the rest of the corals are softies/lps/zoas/clams. I'm looking for a submersible pump around 800-900 GPH.
