Sump help

[gregzz4]

I'm thinking you could use the trapezoid chamber for your drain inlet and skimmer chamber, and have it go under the divider to one side of the back half which would become your fuge
Seal off the bottom of the trapezoid to the 'other' back half chamber, and use it for the return pump, utilizing the overflow of that center baffle
This will give you a decent bubble trap as well
And no adding extra panels, just a quick strip to seal off half of that under-pass

Sorry of there is confusion. The gap on the bottom is only on that one half of the sump. So then trapazoid as return would then naturally flow to the upper chamber through the bottom, would fill that and overflow to the lower as a return? Only question would be is because the bottom is open the sand bed in the fuge would spill into the skimmer area so I might have to throw something in anyways.

Thinking I could use the sealed lower chamber as the sump and the trapazoid as my fuge and just build a baffle and then both would drain into the upper chamber as the return...

Sorry I missed that
So the under-pass is only on the left side
Works well so far

You never mentioned sand ...
Maybe you could add a horizontal piece of bottom glass ( left to right ) in the fuge section, just back from the under-pass ( maybe 1/2 or 1 inch ), and just taller than your sand depth to keep it in place ?
Make sense ?

Hang on, I missed some more of your post ...

I'm trying to absorb what you said, but with all my studying and the heat at work, my brain is mush

What do you think about my idea, or is it totally wrong ?

I see the water coming in the front (trap) then going left, spilling over and leaving from the right

So from what I am gathering from you is coming in at trapazoid on right, flowing underneath to the upper left chamber with the tape measure in it, then flowing over the wall to return in bottom left...

Ya, that's it
We were talking different left/right/up/down
I was thinking of the chambers as they sit with the longest edge against a wall, not the way they sit in your pics ( which is totally backwards anyway )

What do you think ?

[gregzz4]

And just to clarify things
In your third pic, the end of your tape measure is in the trapezoid, and I'm calling the area with your tape the left chamber

Sorry about not mentioning sand. Ya I have thought about a little wall.
