My pool is behaving pretty well this year (only 2nd season we've owned this home and the pool), but two tests seem to change every week. pH keeps rising (have to add ~1/2 gallon about 3 weeks of the month) and CH keeps dropping (added 25# two times in the past three weeks). Am I missing something, or is this just an ongoing battle?
25,000 gallon gunite pool with an SWG. Attempting to maintain pH 7.2-7.8 and CH at 350-450.

I'm adding more calcium chloride than Pool Math tells me to, but still not getting into target range, let alone actual target of 400.
