Settling tank for 500

[takagari]

So I've been looking at cleaning solids.
My 500 has 3 1.5" overflow pipes. Going into the sump presently.
I'm considering adding a cut down plastic barrel.
Have 3 inputs come in. Near bottom. Then 90 to create a "vortex".
Then install overflows in the barrel to sump.

At bottom middle of barrel. Install bulkhead for a drain valve.

In my head. The water.should spin. And slow down enough. That most debris should settle.
Then drain the barrel once in a while.

Has anyone tried this?

I've seen versions of this before on other applications. The trick, which will take some testing, is to get the flow right.
If the vortex is too fast nothing will settle out.
What gpm is going to your sump currently?

Around 2500gph I would guess
