Helps to keep livestock healthy too. Review: Good product. Works as it should. - 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. ## Features - Chlorine Dioxide for onsite generation - 1 individual kit with 2 Single-drop dispensing bottles - High Drop Count: Each 1 oz bottle delivers 600 drops of 4-5% HCl and sodium solution - Convenient Storage: No need to refrigerate, store in seperate bottles in cool dark dry place to support chlorine dioxide longevity ## Technical Specifications | Specification | Value | |---------------|-------| | % Assay of Chemical(s) | 4.0 | | ASIN | B09YL4B2TK | | Best Sellers Rank | #140,135 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #448 in Swimming Pool Chlorine | | Brand Name | CrystalClearlab Chlorine Dioxide | | Container Type | Bottle | | Customer Reviews | 4.5 4.5 out of 5 stars (249) | | Included Components | accu-drop bottles | | Item Form | Liquid | | Item Type Name | camping-chemical-water-treater | | Item Weight | 2 Ounces | | Manufacturer | Family Health Products | | UPC | 850037429134 | | Unit Count | 2.0 Fluid Ounces | | Volume | 1 Fluid Ounces | ## Product Details - **Brand:** CrystalClearlab Chlorine Dioxide - **Item Volume:** 1 Fluid Ounces - **Item Weight:** 2 Ounces - **Package Information:** Bottle - **Percentage assay:** 4.0 ## Images ![Crystal Clear Lab Chlorine Dioxide - Pure CDS Set with Single-Drop Bottles HCl Large 2 fl oz - Image 1](https://m.media-amazon.com/images/I/712w3w0dYFL.jpg) ## Questions & Answers **Q: Should a 1:1 mix ratio turn the mixture an amber color?
