We recently bought a house with a pool, and found out that the SWG wasn't working and FC was at zero when we moved in. After adding LC, we got the FC up to 5.5, quickly thereafter fixed the SWG, and things seemed stable for at least 5 days. Recently FC started creeping up, and I lowered the SWG output a couple of times, and the FC kept rising. I'm curious if the initial SWG setting was really just overly high, or if I'm missing something else that's going on?
Full data is in my pool math logs, but at a high level:
3/31 - FC = 0 ; added LC to get up to ~8 FC
4/4 - SWG fixed ; set at 65% which is where it was when we bought the house
4/6 - FC = 5.5
4/8 - FC = 5.5
4/14 - FC = 8 ; Changed SWG output from 63 to 50
4/16 - FC = 9.5 ; Changed SWG from 50% to 45%
4/17 - FC = 13.5 ; Changed SWG from 45% to 30%. Turned SWG off completely until FC gets in a lower range. If it matters, this was the first day we swam in the pool (wahoo!), so there was load from people for the first time in addition to what's in the pool math logs.
I have added Muriatic Acid a couple of times to address PH/TA, but my understanding is that doesn't impact FC.
The SWG is a Hayward TCELL940 and runs on a single speed pump for 10hrs a day, and the pool is about 14k Gal. Can somebody more familiar with the math involved let me know if the 65% SWG output it started at was just crazy high, or is there a better explanation to the rise?
