Closed Loop without Powerheads?

[fiveplusfive]

I would like opinions/suggestions as to whether this would work or not.

I want to use a closed loop in place of powerheads.

65 gal 36x18x24 want majority SPS

Reeflo Snapper pump 2400 gph
2 SCWDs 3/4"
4 Pacific Coast Flow accelerators 3/4" at end of each return

Would use various pvc piping sizes as labeled. Over the top, without drilling.

Goal of this loop:
1. enough water flow for SPS
2. maximize tank space and ascetics with no powerheads
3. want quiet operation

Will also have sump return around 400 gph.

BTW - Please go easy on the sketch. I'm not familiar with any CAD programs and had to use paint shop pro.

looks good

It seems like you are off to a good start. I think I would continue around front with a couple of outputs there too - you can easily hide the pvc up under the edge of the plastic trim. I hold mine in place with twist ties - i drilled holes in the edge of the trim. Unless you actually stoop down and look up, you cannot see any plumbing at the front of the tank. More flow from as many places as possible is a good thing.

you wouldn't be able to alternate flow on something like this, would you.

is that an issue?

I completely agree. Maybe something like this would be an improvement:

Each SCWD should alternate between the red and blue flows every ? seconds based on receiving 1200 gph flow (less head/friction loss)

Are the flow accelerators needed or could I get by with just T fittings and 90 elbows, or is there a better option?
