To use copper sulphate or not

[aylad]

I think I need to get a good test kit so I can get all the numbers I need at home instead of going to the pool place.

Absolutely!!! That's the best advice you're going to get.....



In your situation with the liquid chlorine, I would go with your 12%. The chain stores nor the pool stores in this area will carry 12%, so it's pretty much bleach for me.
