Water level in return chamber?

[Notsolostfish]

What water level should i have in my return pump chamber for my sump? Someone said that the water level in return pump should be lower than the rest of the sump level?

Deep enough so the pump does not draw in air, and shallow enough so the sump doesn't overflow when the circulation pumps stops (to clean or when the power goes out.) HTH.

Depending on the setup, I recommend filling the display until it flows into the sump, then fill the sump to within 1-2 inches from the top. Once full, turn on the return pump and note the water level once things stabilize (might take a while so be patient.) With the pump running, make sure it’s deep enough not to pull in air and you should be good. Top off to that marked level to ensure a consistent salinity.

This is a generic sump layout

Lower than the tank lever but not exposing any heaters or other equipment. The chart above it great.
