CSI .44 (currently)
CSI -0.32 (if pH were at 7.2)
Crazy that the pH is so high as I've been monitoring and for the last week and a half it hasn't been above 7.4... but I did just put a gallon of chlorine in about 2 hrs ago.
I put a half gallon of muriatic acid in just now because of the high pH and will check pH in a couple of hours to make sure.
I did add calcium during the startup... and at another time but I don't have the records.
Thanks for your response @mknauss . We don't get a lot of rain where I'm at and it gets pretty darn hot. I already fill about 5 min of water (line goes directly to the pool) about once every 2-3 days.With fill water at 90 CH, you should be pretty good for some time. Try to use rain water to refill pool when you get.
I would suggest starting to use CSI for chemistry monitoring as your current CH is getting on the higher end of the normal scale.
I just used the regular CH test, filling comparator tube to 25ml... I should probably start only filling to 10ml for the "high" anticipated calcium test in which case it says to multiply drops by 25 instead of 10. Just for a point of reference, I took a sample to Leslie's the other day to test for metals and they measured my my calcium at 458.At a CH of 570 (how did you test that? Normal results are in factors of 25) you are not in scaling region. If you drained, the lowest the CH should go is 350 ppm. So your stain is not likely to be scale, unless your test results are not accurate.
Yup and yup. At first I thought the trichlor puck worked... but the slam didn't seem to help the stain. The vitamin C test is not easy to perform in the deep end but I didn't see any results... and the Leslie's metals test showed iron at .1ppm and copper at .2ppm.Have you tested the stain with Vitamin C? A trichlor puck?
