The water in a small reservoir like a spa quickly accumulates organic contaminants from bathers in a high-temperature environment. So it’s important to eliminate those organics with a regular dose of oxidizer for healthy water, especially during each use or at least weekly to freshen the water.

Chlorine shock uses high levels of chlorine to oxidize contaminants while Midnight Cove Oxidizing Shock contains no chlorine or bromine. So organics are oxidized directly with oxygen without irritation and odors.

Fragrances are not necessary for sanitation but are popular to complement the experience of soaking in your spa or hot tub. Midnight Cove has perfected the process of combining chlorine-free shock with the many benefits of aromatherapy
in one very affordable package.

While the gentle oxidizing power of Midnight Cove can last for days, the fragrance dissipates over a few hours to avoid buildup under the cover.
