Folks,
I keep a log of my pool for comparison year over year. This year so far I've had to run my SWG at a setting quite a bit higher than last year (but our weather has been weird too). There are some differences and I'm wondering if that is playing into things. Last time I did an overnight drop test it was fine.
I did an ascorbic acid metal cleaning job earlier in the season and the pool looks great, but now of course, I've got iron floating around in my pool. My SWG also reports a much higher salt level than I get when I used a test strip (about 1000 ppm higher than the strip).
So I'm wondering if:
1) The iron and other solids (we have super high calcium levels in our water and I use borax too) could cause the SWG not to run as efficiently.
2) If the SWG thinks the salt reading is so high, is it turning down the current applied and thus getting less Cl into the pool as a result? Any way to recalibrate it closer to the strip?
Thanks!
