This is a hot tub shock treatment. It is not a sanitizer, it is not a veterinary medicine, it is not for laundry. **Q: 2 ounces is equal to how many teaspoons? It’s a dry product but I don’t have a scale to measure** A: I toss in 3 teaspoons every week - 10 days or so. Depends on how many people and how often ! **Q: Where do i add this solution on sundance cameo spa? and how often? after each use or weekly? thank you** A: I put two capfuls fight into the water once per week along with 2 tablespoons of chlorine granulars. All depends on amount of use though. More use more chemicals ! **Q: Does this product have any salt in it? my hot tub was all in sync for 6 months and then i started using this and now the hot tub has too much salt.** A: The potassium salt is a product of the peroxymonosulfuricacid in this product. It is an oxidizer like a chlorine oxidizer, but only to be used in a low chlorine system such as the Nature 2 Mineral sanitizer if you are not using this system then you would need a chlorine based oxidizer. ## Frequently Bought Together - SpaGuard Spa Shock-Oxidizer (35 oz) (1) - SpaGuard Spa Chlorinating Concentrate - Advanced Spa Water Treatment for Hot Tubs and Spas, Quick Dissolving Oxidizer - 2 Lbs - SpaGuard Spa Total Alkalinity - 2 Lb --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/69300655-spa-shock-oxidizer-for-spas-and-hot-tubs-35-oz](https://www.desertcart.sg/products/69300655-spa-shock-oxidizer-for-spas-and-hot-tubs-35-oz) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-11-08*
