Not sure where this should go, but since a SWG is involved I stuck it here. Feel free to move it if need be.
Some background on my pool setup:
I can run the spa in spa-only mode (only the spa has return and suction).
I can run the spa such that its floor return feeds water in, and then the overflow goes over a spillway into the pool, and the pool has all of the suction.
I can run the pool such that it gets all of the return and suction (spa has zero flow).
The 3rd option above is now possible due to a 4th actuator being installed. I can control the spillway via a schedule (even if it currently turns on/off with a tanning ledge bubbler), so I am wondering how much turnover my spa needs. Of course, the PB says that my spa will turn green if I don't circulate it all day. But that seems pretty excessive...
My question is, is there a ratio or calculator to determine the amount of time/turnover the spa needs? If the spa is 1/32 the size of the pool, does it need 1/32 of the flow that the pool receives (not time, but volume of water)? Or is it trial and error, and just see what works?
