New house and a new pool
We inherited a high CH, TA and CYA. I've read around on the site enough (and posted a question) to know that I need to have higher FC because my CYA is high.
Yesterday I put in 4 gallons of 10% liquid Cl,
Today I tested and got the following
100 CYA (I diluted the sample 2:1 with tap water and measured 50 ppm)
I also tested CH but the sample never really turned blue, around the 40 drop point it turned clear.
Now all that being said, I recognize I don't have the best test kit for Cl, all I have is DPD, not FAS. That is on order, so I hope to have a clearer picture soon. but I still expected higher FC today.
Thanks in advance for your help.
