We have an Intellichlor. Our pool is between 25 and 30k gallons. It's a lagoon shape, so we were never sure.
Anyway, this is our second year. We opened the pool and the diagnostics showed 1500 ppm for salt. The intellichlor also showed "low salt". I used the pool calculator to determine we needed to add about 9 bags of salt to get us up to 3200 ppm. Neither of us could remember what we did last year, so we just started with five bags (40 lbs per bag, solar salt). We added them last night. This morning, the diagnostics on the panel shows 4500 ppm salt!
I don't have any strips or anything like that to check it manually. We've always just used the diagnostics on the panel.
Any ideas what the heck happened?
