This non-chlorine shock is the ideal oxidizer for spas with an ionizer unit.  It makes undesirable compounds disappear. Spa Shock is simple to use - just apply directly into your spa water while the pump is circulating. Try Spa Shock in two convenient sizes of 35-oz and 7-lbs.

Buffered monopersulfate is easy to dispense and is applied directly to water while the pump is circulating. Spa Shock dissolves instantly, immediately oxidizing undesirable compounds. In spas treated with bromine products, this product turns ineffective bromides back into active hypobromous acid. It works quickly, so spas can be used as soon as 15 minutes after application.
