    • Works great
Size: 12 Pack Style: Advanced Shock
Works great for keeping the pool clear and algae-free. The cal-hypo formula is strong and effective, but it can leave some residue if not well distributed. Has a strong chlorine smell, but overall a reliable shock treatment.

    • Works great!
Size: 6 Pack Style: Advanced Shock
Just like what I buy in my local store but at a much better price. Will buy again. Very satisfied. Forgot to look at the amount of calcium though but haven’t had any white residue around pool edge or floating in water.
