Won't the non chlorine shock continue to oxidize the contents of the pool even after 1 hour?Pathfinder said:If you bring your chlorine/Bromine levels up high enough and everything else balanced, drain down your pool to winter level then do a non chlorine shock wait 30 mins/ add your stain prevent wait 30/ then add your 60% algaecide.
I still dont understand what your saying. What does "breakpoint chlorination" have to do with anything? Are you just talking about chlorine potentially breaking down the poly 60?Pathfinder said:To elaborate, would you put algaecide in your pool just after you shocked it?? At break point chlorination levels how effective would any chem be being added after. Which is why I use the method stated in the previous post.
Yep. No need to add MPS. Yes, high chlorine will chew up sequesterant and vice versa. You could add an EDTA based chelator, but over the winter, its not that useful to do, it wont last. One/is better off adding bleach to shock levels based on the CYA and close it down. Thats why all those closing kits are a waste of money and make the pool store rich.zea3 said:Won't the non chlorine shock continue to oxidize the contents of the pool even after 1 hour?
