Best: Use up or give away. Dispose of empty container in the garbage.
Second best: If connected to a city sewer system, flush small amounts down an inside drain (toilet is best) with lots of water. Do not pour pool chemicals down the drain if you have a septic system. Contact your local sewer agency to know what is an acceptable small amount for your wastewater treatment plant.
Third best: If on a septic tank or for large amounts, take to a hazardous waste facility or collection event.
Do not mix pool chemicals with garbage or other chemicals. Even a small amount mixed with household garbage can cause a deadly reaction. Dispose of these chemicals properly, according to directions.
Use ozone or ultraviolet light systems designed to kill bacteria and algae.
