Hi!! My pool is out of whack! I just cleaned my salt cell last night because it was saying my salt was low. But after cleaning that light went off. I tested and my chlorine level is at 0 and my pH is at 8.4. Sooooo what do I treat first?! Also what is the best way to raise the chlorine?! We have the little floater but is that the most effective way to do it? I am starting to see little green spots on the bottom of my pool so I'm hoping if I fix the chlorine those will go away.
Thanks for the advice!
