Last year my husband used a copper based algeacide and we are still feeling the effects in our 16 X32 inground pool.
Here is the data: pH 7.3, tot alk 132, total hardness 223, Cu 1, CYA 151, Free chlorine 0.3, total 1.5 . Our water is somewhat cloudy as I still can't see the bottom of the deep end. I have some 12% "bleach" I know I have to add, but wanted to get the Cu down before. Thinking of using HTH metal control.... ANy thoughts? Thanks!
