I have someone coming out to service my salt water generator next week because all the lights are off and it is not producing chlorine. I was told by the guy who set up my appointment that I should shock the pool asap (before the generator is repaired). I have never done this and am not sure what the best way/product is for a salt water pool. The pool currently has zero chlorine but high levels of everything else (calcium, salt, CYA, TA). There are no phosphates which surprised the guy at the pool store on Friday (I had a dead bird in the pool on Wednesday). My understanding is that it is already too hot in Phoenix to drain the pool. I have been adding MA every few weeks for the last month and a half and the pool store told me is because I have old water. Any thoughts? The pool is not green, just cloudy.
