I am having an issue with Pool Math per the two attachments (could not fit entire screen in one capture). It is telling me that "Your target is outside the suggested range". I believe I need to SLAM the pool in the the CYA has been creeping up and is now at .4. This pool is in the direct sun from sunup through sundown so it takes quite the beating from the UV. This morning the FC was at 6.0, CC at .2. With respect to the latter I've read that if the CC is above .2, no swimming. In any event no one was home today although the pump was run for approximately four hours. Information on the pool, pump, below my signature.
At 1800 the following readings were taken:
FC: 3.8
CC: .4
pH: 7.5
T/A: 80
CYA: 35
I am unsure why Pool Math, which is automatically populating the SLAM Target FC field, is stating that it is out of range. I will get the same message if I put a different figure in such as 10, 12, 9, etc., in that same field.
Thank you!
