I finally tested salt. Been waiting because the stupid HTH salt kit comes with strips, is nearly $20 and that's just dum. But H bought one so I opened it and ran the test.
SWG seems to be perfectly happy. It was happy at 20ppm CYA, happy at 40ppm CYA, and now happy at 65-70ppm CYA (I haven't decided what the CYA test really is yet today. Probably gonna pour a few more times).
I'm still working on how long I need to run the SWG per day but have yet to fall below 3.5ppm running it twice at 4 hours each. I'm still only a week into this so I'm not worried about that just yet unless 8 hours per day on a ~5000 gallon pool seems excessive to someone here.
My CH is relatively non-existent. Fill water is ~2-4ppm depending on whether the water comes from the reservoir or the wells in the city (drought status). I read a lot here about calcium scaling on the plates, making the SWG think it's got low salt. Could the soft water be part of the SWG's happiness?
Basically I want to know if I should bother adding more salt right now or if I should wait till the unit codes. Perhaps 8 hours is excessive and more salt will decrease this time?
