Go-to for pool calcium
Have purchased this calcium several times. Much better price than local pool store & delivered in 2 days. Dissolves quickly, yet packaged securely.

Great price, works perfectly.
Working great, exactly as advertised. I followed the simple directions on the box to determine how much to add. Made sure to pre-dissolve in a 5gal bucket with pool water before pouring it in my pool. Measured before and after calcium levels, and the increase was exactly as expected from the directions. I am very pleased with this product. I will say, the full box was only 20LB total so I am doubting the 25LB advertising but maybe it was just mine.
