Sump water level?

[Notsolostfish]

Okay my first time filling my marine x60.2 and a hobbiest trying to tell me that the more water in the sump the better. his system when the pump is off. Is at the absolute max level for his sump. Should i follow what hes doing? Or should i fill only to 3-4 inches of the return pump?

A good rule is dont overflow the sump when pumps are off and this includes the skimmer water.
You want enough water in the return section so the pump does not create a vortex and suck air.

What do you mean skimmer water? Whdn the pump turns off the water goes up anyway in the skimmer chamber no? So lets say my nyos is sunberged in 8.5 inches water. And pump turned off the skimmer chamber water is going up?

sump level should be your skimmers operating water level, providing theres enough in return section

I have an external skimmer. When its pump is off that water goes back into the sump.
It does not apply to internal skimmers, sorry

When everything is off on my systems, I had about 1” of extra space in my sump. Never had any issues with it overflowing. Plus, this gave me plenty of water over the return pump when running to prevent it pulling in air.
