    • Good pool shock, no surprises
Size: 24 x 1 lb. Bags
Works just like you'd expect granular calcium hypochlorite to work. Effective shock, no clumping, and relatively easy-to-open pouches. It dissolves relatively quickly in a warm pool, but does require a bit of brushing. (If you've never used a calcium-based pool shock before, do your homework. It can bring up the hardness of the water, and if you already have hard water, it can have side-effects. Otherwise, it's a great, shelf-stable alternative to sodium hypochlorite.) ... show more
