When people use spas, they leave undesirable compounds like body oil, perspiration and cosmetics that can irritate skin, burn eyes and create odors. Oxidizing, also known as shocking the water, removes these undesirable compounds and restores water clarity and comfort. An oxidizer should be used weekly in most residential spas, more frequently in heavily-used or commercial spas.


Enhanced Shock™

Every spa needs to be shocked to eliminate undesirable compounds that build up with use. Enhanced Shock allows you to quickly shock your spa and re-enter in just fifteen minutes as long as the free chlorine is between 1-4 ppm. It also offers additional benefits—like keeping the water sparkling and fresh. Enhanced Shock is available in several sizes—including a new 5 lb. bottle.

This multi-purpose oxidizer is perfectly formulated for spas. Each ingredient in this blended product performs an important role:

  • The non-chlorine oxidizer breaks apart chloramines and reactivates bromide ions.
  • The dichloro oxidizes undesirable compounds and removes odors.
  • The flocculent/clarifier helps filter out particles which don’t oxidize easily.
  • The pH buffer prevents drastic changes in the pH balance.

Enhanced Shock is effective and easy to apply. Spas can be used again as soon as the chlorine residual drops to 4 ppm.
