We had a 14,500 gallon fiberglass SWG completed last August, kept it open until October last year. We had our pool guys open it up in April but being in Chicago, our weather was awful and we really didn't open it up until a couple of weeks ago. Our free chlorine level has been sky high (reading 10 on our available testing at home, 15 at the pool store when I took the sample in). The person at the pool store said just open it up and the sun will burn it off or you can try Chem-Out. I did a couple of pretty good doses of ChemOut without a difference and we have been leaving the pool open every day unless it's raining. Today was the first super sunny day in a week and I was hopeful but after 7 hours of direct sunlight, still no change. Our SWG does not have the ability (that I'm aware of) to change chlorine %, it has those pH and ORP probes instead.
Our CYA is super low (like 25), not sure if that is related. The pool person said bring the chlorine down, then deal with the rest of the chemistry.
Obviously, this is super new to us and I feel so dumb right now. The learning curve is steep over here. Please help...
