I thought about that when I first plumbed it but the extra water volume is produced by the sheer volume of water the pump itself is moving into the tank. I can raise the plumbing as much as I want but the pump will still create an inch of water over that height. That inch of water will then make it's way through the system into the bottom sump.

You could add an 90 degree elbow fitting to your return pump with the opening pointed down to allow a lower water level if so desired. I had to do that with a return pump to avoid it sucking air.

Yes, the pic helps! I think you made your sump too short in comparison to the height of the equipment.

I have this on most of my pumps so they can have lower water level.

I would try with some long radius 90's but not the typical 90 elbow. The owners manual for these pumps has a big red X on a pump with a 90 on the intake side. Abyzz doesn't sell the 90 for the intake side like red dragon does. They obviously must not want it used on their pumps. The do sell a slotted 6" straight tube that fits on the intake.

Hmm ok. Is the slotted one only slotted on one side, so you can put the slots on the underside? that might help a bit. I'm not sure if that would give you as much space as you're looking for though.

I can only just get the skimmer cup out as it is. Any taller and that would be a no go.
