Hi I’m new to this and this is my first pool ,I’ve been following the pool math and my pool has been looking
awsome.
FC 3.5
PH 7.5
TA 70
CA 175
CYA 40
I’m trying to understand the CSI, mine says it is -0.55, from my understanding according to Pool Math calcium should be between 250 and 350, My tap water calcium is only 50 ppm so I had brought it up to 175. But I also read if you have a spa to keep calcium lower. But I don’t think my CSI is correct, my alkalinity was at 110 out of tap, was dealing with a bit of a high pH in the beginning so I have been adding acid according to the pool math, now I am at the lowest end of 70 Alk, was trying to keep pH close to 7.5 because I was getting a Little bit of white scaling on my one by one tiles just on the spillway.
Should my pH stay stable now or will I have to continue to add acid ?but then I’m worried about alkalinity dropping too low.
How do I minimize the scale buildup because I don’t think my CSI is right ?
Just trying to get everything on point thanks for any help you may have��
