SPA SHOCK - BUFFERED NON-CHLORINE (7 LB) 42626BIO SpaGuard
Buffered monopersulfate ( MPS ) 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.
