Ok been slamming. CYA 50. FC 20. Last two nights have lost no chlorine. Yes I use well water. I have tested it many times and iron count is very low. No rust in tubs, etc. Replaced pump years ago and well guy was shocked the pump looked new!!!
Anyway, I have had a pool for 4 years. I don't remember ever having this issue before. This time I have followed slam to a T. My water over the winter did not lose its CYA which was odd and new.
I need an opinion of this photo. I wonder if this is not algae. But iron. I wonder if I let FC drift down to 5 ppm it will go nice blue like it usually is. Or am I screwed and have to do Polyfill?
