I am curious what the gurus on this board recommend for CYA levels in Phoenix. I have read in other threads that it should be somewhat higher than less sunny areas. My pool has minimal shade. Specific questions include:
1. What target number should I shoot for?
2. Since my pool is brand new and being filled with CYA zero water, is there really any point in testing CYA early on if I put the recommended amount in? i.e. if I know the volume of water and the number of pounds CYA, then the calculated concentration has to be correct, right???
3. Can someone confirm that I cannot use a standard chlorine test kit if my CYA level is high, because my FC will need to be over 5 and the standard FC test only goes up to 5?
