My wife has been taking care of pool why I am at work. After 3 weeks away things looked pretty good. Crystal clear water.
Initial test on 5-21-14
FC 9..... this was high because of mis-communication on which way to turn output, she went up, no down
CYA 50.........we had tons of rain while I was away.
So based on the CYA level I have added 10 oz by weight of stabilizer. I know pool math says 23oz to go from 50 to 75 CYA. Just dont want to overshoot. I know going in to this that my PH will go down as I add the stabilizer..
So which of the three is best to use for raising the PH? Borax, soda ash or washing soda?
I also see that borax one will add borates to my water. and the other two won't
Which brands of washing soda or soda ash?
