Silk Balance Shock Gems spa oxidizer tablets — Single-dose MPS non-chlorine shock, fast-dissolve (1-2 pack dosing)

Shock Gems by SilkBalance are single-dose, non-chlorine oxidizer tablets designed to remove body oils and organic contaminants so spa water looks and feels cleaner.

Silk Balance Shock Gems are an MPS (monopersulfate) based oxidizer crafted for hot tubs and spas that provides a chlorine-free option to refresh water after use. Each gem is a measured, single-dose packet that dissolves quickly, targeting organic load from bathers — such as oils, lotions, and perspiration — to reduce odors and help maintain sparkling, more comfortable water between routine sanitizer treatments. They are simple to use and formulated to work alongside your regular sanitizer system without adding chlorine.

How do Shock Gems improve spa water after bathing?

Shock Gems break down organic matter that builds up during use, removing the materials that cause cloudiness and unpleasant smells. By oxidizing these contaminants, they help sanitizers work more effectively and restore clearer water faster than sanitizer alone.

• Single-dose formulation for predictable results every time
• Targets oils, lotions, sweat, and cosmetic residues
• Non-chlorine oxidizer — compatible with chlorine and bromine systems
• Reduces short-term odors and visible cloudiness

When and how many Shock Gems should I use?

Dosage is based on the number of bathers: use one gem after soaking if up to two people used the spa; use two gems when three or more people soaked. Toss the gem(s) directly into the spa water after draining or immediately after bathing for a quick oxidative treatment.

• 1 gem: after soaking for up to two bathers
• 2 gems: after three or more bathers
• Best used after heavy use or when water becomes cloudy or odorous
• Allow proper circulation and filtration after dosing

Will Shock Gems affect my sanitizer or spa equipment?

Shock Gems are formulated as a non-chlorine oxidizer and are compatible with most sanitizers, including chlorine and bromine, when used as directed. They won’t add additional chlorine residual, and because they are single-dose and water-soluble, they won’t leave gritty residue when fully dissolved.

• MPS-based — oxidizes organics without raising free chlorine levels
• Single-dose packets dissolve cleanly with normal circulation
• Safe for use with typical spa materials when instructions followed
• Helps sanitizers work more efficiently by removing organic load

How quickly do the gems dissolve and show results?

Shock Gems dissolve rapidly in circulating spa water and begin oxidizing organics immediately. Visible improvements—reduced odors and clearer water—often appear within a short time after dosing, though filtration and circulation will speed the clearing process.

• Rapid dissolution in warm spa conditions
• Oxidation begins on contact with water and circulation
• Clearer water and reduced odor usually follow within minutes to an hour
• For best results, run jets and filter after dosing

Who this is for: Silk Balance Shock Gems are ideal for hot tub and spa owners who prefer a non-chlorine oxidizer to refresh water quickly after use. They suit households with frequent short soaks, small gatherings, or anyone wanting a single-dose, easy-to-measure solution to remove body oils and organic debris between standard sanitizer treatments. If you maintain a regular sanitizer schedule and want a simple way to reduce cloudiness and odors without adding chlorine, these single-dose MPS shock gems are a practical addition to your spa care routine.
