Had my PB open the pool on Tuesday. I knew they'd put algaecide in, they always do. They use one with no copper so I've always just let it go. But I just got the invoice and they also put in something called "Stain Stop." What the heck is that. I've googled it and don't see it. This is summer 9 of the pool and we've been using TFP since Day 1, so I know I don't need it. I just want to know what it is.
Now I'm going to have to let them know next year not to put in anything. The algaecide + the Stain Stop came to $51. 51 bucks for useless stuff.
