Description

FreshWater® MPS Chlorine-Free Oxidizer (sometimes called Spa Shock) is a non-chlorine oxidizer shock treatment that eliminates odors and reduces irritating contaminants to leave water sparkling clear. This works similarly to Chlorine Shock but does not replace ozone, chlorine, or bromine.
For best results use Chlorine on a weekly basis and shock 10 minutes prior to using your spa.

We offer both a 2lb and a 5 lb container of Oxidizer for your convenience.

Please note due to limited supply you may only purchase one per order.
