This 2 oz size is more economical…more so than the 0.75 oz.

This is the genuine Taylor replacement reagent for testing cyanuric acid, and it works exactly as it should. I use a Taylor test kit to keep an eye on my pool chemistry, and having fresh reagents gives me confidence that my test results are accurate. The bottle is easy to use, pours cleanly, and the 2-ounce size lasts a good while with regular testing. I make it a habit to replace my pool test reagents every year, so this was a perfect replacement. If you use a Taylor test kit and need to test your stabilizer (CYA) level, this is a quality product that I would definitely recommend.

I really like the larger bottle so I can test more than once a season. Seems to work, as I did get a reading that matched my previous bottle that came with my Taylor kit. Happy with this purchase.

Taylor Technologies products are my go-to for stability and reliability. I have several test kits to keep my pool balance myself. Saves me from traveling to the pool store so often. I take a water sample in the beginning of the season; after that I can rely on my at- home testing reagents and kits. This year I encountered a CYA too high, so needed extra reagent.

Taylor kits and products make pool water testing easy

The product is good quality but the CYA test uses a lot of reagent. I only got a few tests out of this bottle. Buy the bigger bottle for 15-20 bucks and it will last about a year. I only test CYA periodically and after heavy rain because my pool is salt.

Wonderful product, it’s what my pool company uses. Works great and easy to use.

QUICK SUMMARY: If you're shopping for this product, you already know a thing or two about testing your swimming pool water. This larger bottle is necessary because the smaller, 0.75oz bottles are only good for just a few tests. You may get 10 tests or so with this larger bottle. DID YOU KNOW? Performing the CYA (stabilizer) test can be difficult because it's sometimes hard to discern exactly at what point the black dot at the bottom of the test tube has completely vanished. But did you know that you can re-run the CYA test over and over using the same test water mixed with this reagent? All you need to do is pour back the contents that are in the test tube back into the bottle you used to mix your water sample with this reagent. Shake, then re-pour the same water back into the CYA test tube to take another reading. Run the test a few times and take an average result, if you'd like, and then assume that average is your CYA level. Also, did you know that cyanuric acid will stay in your pool indefinitely? Unlike other chemicals in your pool, cyanuric acid doesn't get consumed or used up. It stays in your pool, acting like suntan lotion for your chlorine. The only way your CYA level will go down is through splash-out and backwashing. Because of that, you don't need to test your CYA levels very often. They won't change much (unless you use stabilized chlorine pucks, which add stablizer to your pool). You may want to do it just once a month or every other month. So, a 2 oz bottle or reagent like this product should last you a very long time -- at least through one full swimming season. Enjoy your pool!
