Sanitizer IS Step#3. Do not Increase/Decrease recommended dosage. Love the way this product works. Keeps water clear as a bell. Very “skin” friendly. Enjoy. **Q: How long will this product last?** A: There is a “Start-up” procedure (3 oz per 150 gallons) and there is a “Weekly” procedure (1-3 oz per 150 gallons depending on spa usage). So, it depends on how many gallons in your jacuzzi and how often you use it. **Q: Is this the same as Baquaspa oxidizer?** A: Correct-replaces the Baqua Spa Oxidizer product that has been discontinued, but same 7.5% hydrogen peroxide and usage steps. Made by the same manufacturer and basically a refreshed branding, is my understanding. **Q: It says this 7.5%h2o2 & water. can i just mix 7.5 oz. of h2o2 with 92.5 oz. of water and replicate this product?** A: The container is 32 oz. 7.5% of 32 oz. is 2.4 oz. You'd need to mix 29.6 oz. H2O with 2.4 oz. H2O2 to make the full 32 oz. I'm not sure if the H2O is just ordinary water or distilled water. Try it and see. It's definitely a lot cheaper. ## Frequently Bought Together - Sirona Spa Care Simply Oxidizer (32 oz) - Sirona Spa Care Simply Sanitizer (82317) 16 oz. - Spa, Pool and Hot Tub Non-Chlorine Liquid Sanitizer for Clear, Clean Water - Sirona 82106 Simply Waterline Control, 32 oz --- ## 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.hr/products/452606829-sirona-spa-care-82137-simply-oxidizer-32-fl-oz](https://www.desertcart.hr/products/452606829-sirona-spa-care-82137-simply-oxidizer-32-fl-oz) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-08-25*
