Just one question: Why do we spend all of this time, effort and money on chemicals to bring it to shock level only so we can cover it, turn the pump off and let it turn green again?
Pathfinder said:If your pool is at shock level when you add other chems they are basically rendered useless.
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.
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?
