Your pool stays clean and clear with hth® sanitizer products, designed to effectively guard against bacteria, algae and other organisms. We offer two types of chlorine-based sanitizers: stabilized and unstabilized. Application instructions: Use in a floating dispenser, automatic chlorinator or feeder designed for this product or place in skimmer. Do not place directly in pool. This may cause bleaching of vinyl or painted pool surfaces. If using an automatic chlorinator, ll the chamber[s] with hth® dual action 3” chlorinating pucks and adjust the ow rate, according to manufacturer’s recommendations, to maintain proper chlorine residual. Adding hth® dual action 3” chlorinating pucks to the pool’s skimmer basket is an alternative chlorine feed method. For clear pool water, follow our 4 step pool care program: Step 1: Test and balance pool water, Step 2: Sanitize, Step 3: Shock at least once a week, and Step 4: Add algaecide as directed.

The pucks control both Chlorine and Algaecide in my inground pool. I have tried other products but none work as well as these. Another plus no need for two separate chemicals.
