Yes, or turn down the SWG output.
FC was still at 9 as of this morning even after decreasing the filter run time to 4 hours at slow speed. It was previously set to 50% and I turned it down to 30%. Is there a way to determine the right amount?
I throttled back the amount of water going through my spa and it slowed down the pH rise quite a bit. Instead of blasting across the spillway 2" deep, the water is under 1/2" deep and it doesn't hit the pool with as much velocity. And it's still ample circulation; no algae ever.Sometimes it is what it is. However, if you find the answer, I'm keen to apply it to my situation.
A year and a half post construction, I continue fight the constantly-rising pH bogeyman due, in (large?) part, to SWG-chlorinated water cascading from the raised spa into my pool. Even with my TA at 55 (or apparently somewhere between 50 and 60), my pH will rise from 7.3-ish to 8.0-ish every 3 or 4 days.
