Chlorine & Bromine takes great care to offer the highest quality pool chlorine products at the lowest prices. We carry 3 inch and 1 inch tablets, and cylindrical skimmer sticks, both made of 99% Trichlor, in a slow release formulation. Calcium Hypochlorite tablets are available for commercial pools with Cal Hypo feeders, and we also have New Water and Frog chlorine cartridges.
