Aqueon model 3 sump Berlin water level

[Tgronenthal]

I'm setting up a 90 gallon reef. I've set up my Aqueon Model 3 sump using the Berlin method. I'm curious if my water level is good?

I've set it up per the instructions from Aqueon but don't know if I did it right. The water level is the same across all chambers.

Please let me know what you think.
