Hello,
I have had my swimming pool for 10 years, the last 2 years has been a nightmare for me. Let me get into specifics - My Total Chlorine Level is currently 10 ppm which is pretty high, but my free chlorine level is 0. I go to the swimming pool store they sell me a non Chlorine Oxidizer and said to put this in and it will help your fee chlorine level. Nothing once again. I also noticed my steps seem to be stained Greyish color maybe even Yellowish Grey.
So here are my numbers
Free Chlorine 0
Total Chlorine 10
Alkalinity - 70
Ph 7.5
Hardness 150
So to me it seems like everything is fine, but those stains and I cant figure out why I cant see any Free Chlorine Levels. And that staining on my steps and around the edge of my liner seems strange too.. I have all my metals checked and none present. I can not use a brush to get that stain off my steps, but a Magic eraser will take it off. Any help would be greatly appreciated. Also my pool is in ground 18X36 roughly 25,000 gallons and I use a sand filter and it has a Vinyl linier.
