What sump water level for vertex 150 skimmer?

[Bigfish of La.]

I have an Omega Vertex 150 skimmer that I'm installing in a sump with a water level of 10.6 ". What level are you using to get the best performance from the skimmer? The manual says the level should be 7" to 9.5"and I need your thoughts. I will have to build a stand to elevate the skimmer and would like your opinions.

Thanks

I’m at 7.5 inches and have good control over skimming wet or dry. I started at 9.5 but it always was wet skimmate so raised it with a starboard platform.

Here’s a pic showing the water line in reference to the riser tube body where it runs the best.

Thanks for the reply.
