I have a 40,000 salt water pool. On opening the concrete floor and walls all have a blue stain (normally white). I just had the water tested and the chlorine level is 18, hardness is 166 ph 7.9. Prior to this I used magic jack stain test and it appeared that the copper stain kit with shock removed the stain.
I just bought Metal-out plus and poured it in the deep end and will wait until tomorrow to see if the stain is gone. Meanwhile, Why would my chlorine be so high, I have my salt cell generator set at 50% and just turned it down to 10%. How can I lower the chlorine without draining the pool. I am so confused! Thanks in advance for any help!
