Bean is done, plumbing finished, sump done except for the sock holder plate. Need to start working on the return pump and get some rock curing.

Just out of curiosity: Why the gate valves on the two emergency drains?

No you are correct. Bean states the two (open and emergency) lines don't need gates, but he runs them, so I threw them on.
The elbows in the box SHOULD follow that configuration, but the reality of where the water level lies in the box requires some tweaking. A tip here, a spin there. In my pic, they are in arbitrary positions.

His overflow box is a custom coast to coast. My is quasi-custom, so there's a little guesswork on where to drill the holes in the tank. Matching that up with the box. Modding the trim, etc. I'll just have to wait till there's water in there and adjust. I'll put gutter guard over the top to prevent critters from getting in. Bean puts the elbows in the box about 1/4" off the bottom to prevent snails from getting in. This one just didn't work out that way for a few different reasons.

Really wanted to, it was a bullet proof sump. This is under the tank and it left me no room. I'm going to run a calcium reactor under there too, so I had to redo the sump situation. Will still be tight, but workable as the stand is 36" tall where the tank sits. Lotsa headroom.

Really struggling with return plumbing. Can't decide how and where to put it. I don't want to drill any more holes, so I've got to go up and over. Thinking I'll need to go into the corners.
I have 2 MP 40s I'm going to use on the back wall to try to create a "barrel roll" gyre. Just not sure how well the small center box will surface skim on a 2' x 4' water surface.
If done correctly it should roll back into the box. If I plumb flow in the wrong direction, I'll be fighting my own purposes.
Here's what I've got preliminarily. VERY preliminarily.
Open to suggestions!
Also, can't decide on all PVC, spa-flex, or combo of hoses & PVC. Any one better for reducing head loss?

Might be heading that way. Thus configuration has way too much head loss. Gotta scrap it. Back to the drawing board....

You just use the same fittings as normal sch 40 PVC piping, primer, and adhesive right? Never used it before.
Yep.
edit: didn't see Jackson's post. I had a stale page....busy booking flights to Florida...yyeeeaaahh

Ummm Pretty sure corners are corners no matter what you make them out of when it comes to that. The thing that's gonna make a difference is a 45 vs 90 degree bend. I could be wrong

I may end up drilling 1 return hole and over simplifying the return schematic.

I went with 1" spa flex but had a few long bends. I have 15 or so feet left over if you are passing through Rochester any time. I could sweeten the deal with frags if needed... I just finished my 120 tech redo after the move so I'm anxious to see what you do with yours. Looks like you are off to an awesome start.

I've read, for whatever reading is worth, that the difference in loss between a 90 and a 45 is pretty negligible.

I would use that configuration, just flip it so it points from the front corners to the overflow box.
Put those MP40's low on the back wall and you should be in business.
