I've just started doing my own chemicals and need help. I have a vinyl-lined 29,000 gal pool, SWG. Have had a SWG x 2 yrs. Just got a new cell; old one never really read things correctly.
My chemicals have been off for a month. Today, ph 7.1, FC 0.5, CC 0.5, T/A 100, CYA 110.
I've used the pool calculator, but was trying to avoid draining the pool.
Per the calculator, I've added dichlor daily for the past 2 weeks to get FC up daily. I'm not sure if I should shock, or to drain to lower CYA. What problems result from elevated CYA?
