Hi.. Thanks for helping me over my 20 years of pool ownership!
I think I have a very chlorine resistant form of pink algae. I slam, brush and pass the test and then a day later the pink haze comes back, bigger. Started with two small 6 inch areas. Yesterday, it was spread over the shallow end floor. Light colored pink haze. When I brush it, it goes away.
Started a slam last night again using cal hypo. Free Choline measured 9.6 this morning. Very light haze this morning. Water VERY Clear. What to do? Yellow Out? Is it safe to swim? (Grandchildren!) Reading pink algae is bacterial based?? Where does this come from? Thanks!
