Shock Gems by SilkBalance When it’s time to shock your spa, our Shock Gems are the convenient solution because the tiny one-ounce pods are specially formulated to work in conjunction with the SilkBalance water conditioner. We’ve taken the hassle out of keeping your spa clean with this new, handy, non-chlorine chemical alternative. ELIMINATE ODORS AND REDUCE ORGANIC CONTAMINANTS with these convenient, single-dose MPS shock gems Because SilkBalance is not a sanitizer, you still need to oxidize any organic contaminants in the spa. Simply toss 1 Shock Gem in your spa after soaking – for up to two bathers – and 2 Shock Gems for three or more bathers. (You never need to add more than two Shock Gems at a time.) This removes organics such as body oil and perspiration and helps prepare your water for the next use.
