Taylor R-0013-E Cyanuric Acid Reagent, 16 Ounce, Price/EA

Got this reagent as part of a Taylor kit, noticed how much I had to use and was glad to find this bottle available... It is a little pricey, but 16oz should last a while at the rate I need to test CYA. The cancer concerns from other posters seem a little reactionary to the label without doing any research. From what I have found on the reagent is basically Melamine which gets used in various products and can make its way into foods. Now when you mix it together with Cyanuric Acid (which you're doing in this test) it creates Melamine Cyanurate which is a little more concerning as the dosage required for a LD50 drops 50. However the levels in your pool water sample should be relatively low PPM. Even if it was 100 concentration the test sample isn't immediately lethal. It would take regular exposure at these levels or higher volumes to start becoming a concern. By exposure it looks like ingestion is the main concern. So refrain from drinking the solution and you should be ok. Regardless, you should be wearing gloves, mask, and eye protection when handling most pool chemicals. This chemical along with all the reagent testing is no different.
