Went on vacation for 2 weeks, turned off filter, although I have a timer on my pool (I didn't have anyone to come over to clean skimmer). Came back to green pool, I shocked to 15 since my cya is 30, after 4 days, pool was back to blue to but cloudy. I can see low end but the deep end is cloudy. I have been running my filter for 24 hours 7 days now. Here are my numbers:
fc = 20
ta = 120
cya = 30
Should I increase the ch - I haven't touched that since I have a vinyl pool and when I tested no calcium was present.
