I am having a problem with my ph and alkalinity continuing to drift up. Every time I lower the ph to 7.5 it just jumps back up to 8.2 or higher (can't tell higher from the kit) and the alkalinity drifts up with it. I got them both down to 7.5 and 90 respectively but they went right back up. Any ideas about what could be causing this and what I can do about it. I use liquid chlorine. We have had the pool for five years and this is the first time I have had this problem.
My numbers are
FC: 4
CC: 0
TC: 4
ph: 8.2 (or higher)
TA: 120
CH: 110
CYA: 50
Temp: 79
Pool is 18,000 gallons, vinyl.
