Squire's 90 Gallon Build, Now With Salt Water

[ensquire]

Issue #3) Sump flow, I know the goal that all drain water should run through the skimmer before going to the return chamber. With that in mind I decided to see if my sump would make that possible. What I found is that either my pump is to big, or in combination with my drain problem, I can't throttle it back enough for the skimmer to handle the flow. My pump is a Waveline 5000 with 1300 GHP but I run it at half so probably 700 gph . The sump can handle full throttle but the skimmer can't. It's a SWC Cone 160. Not sure of handling capacity for skimmer . If I throttle back the drain enough for the skimmer to keep up, then the drain gets really noisy from all the air through the gate valve. So if I can solve the drain problem to some degree I can solve this one. Although I would like the most water flow thru the sump.
Can I live with not all the water not getting skimmed??
Can I mod the skimmer for more flow ?
Making this a herbie won't solve this one

I wouldn't be so concerned about all the drain water going through your skimmer
If you sat down and calculated what it takes to cycle your whole tank through your skimmer, you'd agree
Keep your return water flow where you want it. 5 - 6 times or so per hour is fine.
My 75g, with 110g total water, flows about 650gph. I've been told that's lots, otherwise the socks and skimmer can't do their job effectively

The rest of your flow happens inside your tank

If you're thinking about 15-20gph flow, that's the total of everything with a full-blown SPS tank, not what runs through your sump, and not what a new tank needs

You and I only need about 10 times per hour to start with, give or take

When the tank is running Mike, where is the water level inside the OF box? From my experience with the durso the top of the Tee where it meets the 90 should be just below the bottom of the teeth on the overflow and your water level should be about the halfway mark on the tee to 90 section. I also cut down the top of the tee as short as possible and have cut the 90 end facing down shorter as well.

When the tank is running the water in the overflow is maybe a half inch below the teeth, so 3/4" below tank water level. the Tee / 90 intersection is at almost that same height, 1/2 to 3/4" below teeth.
I will mod the Tee and 90 and see where that takes me.
Thank you ol' Mighty King of the Durso.
