Please help if there is a solution with my sump

Gotcha so this is my water level in sump with all power off. It is about 3" from the very top rim.

Yep, you can add at least 2 more inches and still have some room to spare. Just make sure to mark the line on your sump so you don't overfill.

where does your return sit in the tank?

On the far right those 2 blue pipes

When I use a ATO sensor do I put the sensor in the first section or where the return pump is?

Where the return pump is. That is the only section that should fluctuate.

Yes. ATO sensor goes in the return pump chamber as this is the only place where the water level should change while the pump is running.

You sure it's not back pressure from the return lines filling the sump back up?

When power shuts off yes there is sign from return lines but those break siphon eventually. I guess I could drill a siphon just below waterline to break siphon on one of the returns since I have 4 right? But I really didn't want to do that but realize I might not have a choice because when I turn my skimmer on it sucks a lot of water up and makes the pump kinda start sucking air.

That's what's filling the sump so high . Raise one line at water surface .

Ok I van

I'll put a rubber block under one of the returns on the tank rim and hopefully that helps.

Yay! It worked!! I temporarily put a 2x4 under the 2 outer returns. Here is what my sump looks like now!! Yay!!!
Using the tank calc I can now add an extra 17.29 gallon and still have 1.25" inches from the top.
This is what my returns up top look like with temp wood lol. Do I only have to put it on 1 side(1return)? Is what I ok or acceptable?
Thank you all for the time to help me out. Much appreciated!
