Hrm, I’m trying to understand what you mean by a slip bulkhead screen. Just something like this?

The 45 I understand, and you have it just high enough that you get the water level you want in the overflow box with barely any water going into that secondary?
I’m definitely willing to play around. Looking at the weather forecast it seems I have about a week.
And interesting that it will be different with saltwater. I could understand that the final valve position would be different, but I assumed if I can’t make it silent on freshwater, I won’t be able to make it silent on saltwater?
Yep exactly that pictured and correct on the 45. And it’s not even a requirement more just for warm and fuzzies that a snail or something could somehow get into the overflow box and in the main drain. Heck the synergy has nothing to stop that.
