BITOUSHI 20 lbs 3 inch Chlorine Tablets — 99% Tri-chlor, 90% Available Chlorine, Individual Package

Powerful pool sanitizer formulated with 99% Tri-chlor and 90% available chlorine to purify water, prevent algal growth, and keep your pool sparkling clear. These 3 inch tablets are a slow-release, long-lasting solution that consistently dispenses chlorine over time — each tablet melts in 7 days. Gentle on skin: the formula does not contain irritating ingredients, so swimmers can enjoy the water with less worry about sensitivity. Floating design allows tablets to move freely and treat the entire pool surface for even sanitation and consistent color without hard-to-reach spots. Versatile cleaning use beyond pools — suitable for maintaining cleanliness in kitchen sinks and toilets as well, delivering an all-around sanitizing effect.
