Hi! I am trying to find out if the copper in the new HTH pool chemicals are going to hurt my pool. I bought some the other day at Home Depot on a whim. Leslie's gets expensive after a while. I am moving towards the method this site talks about but for now.....is that copper going to hurt anything? Will it stain my pool? I just bought a 5 lb. bucket of their 3" tabs, some PH Minus, and Shock and Swim. I didn't notice the copper listed until I got home. I have been using the usual stuff from Leslie's
(I used the 3" Trichlor tabs from Leslie's).
