We are trying to reduce the CYA in our pool and have a very good Taylor test kit but they only give you enough reagent to run 4 or 5 tests. We definitely needed more and this large bottle was the answer. it seemed to work great and I could refill the little bottles that came with the test kit.

Just so you know, this is only the reagent, this is not the whole test for cyanuric acid levels!We chose to use liquid chlorine and a chlorine stabilizer (cyanuric acid) for our pool this year and we previously purchased a Taylor chemicals kit. This cyanuric acid reagent ran out on the kit so we ordered this large one to make it through the summer. It's very accurate, my pool has not turned green using the results from this reagent to calculate my chlorine and I'm happy to say the price on this size was much cheaper than the smaller sizes.Cyanuric acid acts like a sunscreen for chlorine so it's important to check this so you know how much chlorine to add.

Taylor makes the best and this is worth the value for refilling.

This is fantastic as you need a lot of this product to do the test. Nice large size i wish it was a smaller top.

Recommend you keep it in cool/dry place to extend shelf life

Bought this as a larger refill option to test CYA for my pool. Worked perfectly and provided me with accurate results. Glad to have found this larger bottle, should last me at least 2 seasons.

Good for checking CYA does the job right.

Of the chemicals you use to test your pool water, this one is used by the half-ounce, not by the drop. So it makes sense to buy this big bottle -- if even just to refill the small bottles good for two tests. I need to monitor my CYA levels because the floater tablets add significant CYA as they dissolve. Will be using a couple of approaches to lower (and calculate) my CYA levels to get another year before having to fully drain and fill the 15,000 gallon. Particularly important because the price of water in my city is high.

The price for this volume is well worth it. Cheaper than others by far. Arrived earlier than indicated and well packaged. The product's expiry date isn't for like a couple years so not like it is old stock or anything. I was skeptical at this price per volume if it is genuine Taylor product. However, the label looks legitimate and the reagent worked fine. My test results were in line with other test sources I have had tried so I am satisfied the product is legit and works as it should. At the time of purchase (July 2021) I paid about $25 for this 16 oz bottle which is over 60 CYA tests over the next couple seasons. That is a great deal!

Expensive and life span too short.Expiry to short you would never use the whole bottle before the expiry date unless you are commercial use.
