Even the prophylaxis dosage (see Kalcker) is drying - eat fatty foods to compensate ### ⭐⭐⭐⭐⭐ Well worth the price for the convenience *by S***E on January 19, 2026* Great product and easy to use. Works excellent for killing germs and viruses in water and containers. I also use it to help my pets get over illnesses. Public water treatment departments use it for sanitizing water systems. Helps to keep livestock healthy too. ### ⭐⭐⭐⭐⭐ Good product. Works as it should. *by A***7 on March 8, 2023* I am updating a previous 1star review where I stated the formulation must be off because it did not turn the correct color. I tried another brand, and once again, the clear glass on the white counter top did not reveal a properly activated color. Therefore my method must be the issue, not the product. I changed to a white ramekin and tried again. This time it turned to the correct color. I did shake the bottles before I tried it, incase it needed to be mixed first. However that is not something I normally need to do. Regardless, I used it and the water did not have any weird taste like some other brands do, or like the citric acid version does. I am updating my review to 5 stars. I love that it has worked out because I love the eyedropper bottles. Such an accurate way to measure. Included picture of the ramekin so you can see it turns to the proper color. ## Frequently Bought Together - CrystalClearlab Chlorine Dioxide Solution Kit, Part A Sodium Chlorite and Part B Hydrochloric Acid, 1 Fl Oz Each - DMSO Pharmaceutical Grade with 99.9% Purity & Low Odor - 3.38oz (Dimethyl Sulfoxide) Glass Bottle with Dropper - CrystalClearlab Chlorine Dioxide Kit | Hydrochloric Acid 4-5% (HCl) : Sodium Solution (8oz) Liquid Set --- ## 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.hk/products/430938745-crystal-clear-lab-chlorine-dioxide-pure-cds-set-with-single](https://www.desertcart.hk/products/430938745-crystal-clear-lab-chlorine-dioxide-pure-cds-set-with-single) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-07-13*
