Hello all. I guess its that time of year to get the pool ready. My pool is clear and 68 degrees. I've tested my water and its as follows.
I'm testing with a TF100 kit I got last year and according to the Pool Calculator, I added 16 oz of M. acid to lower Ph. When I tested for chlorine using the R-870 powder, it wouldn't turn pink. I used the blue test block and it showed 0 chlorine also. When I tested for CYA its low like 0. I will adress the CYA levels next and carefully raise chlorine.
What does it mean for the water and R-870 solution to not turn pink? No chlorine?
