TAYLOR TECHNOLOGIES INC R-0013-E CYANURIC ACID 16 OZ

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.

Item came on time, was NOT expired and was sealed. The price was good and I would order it again

Economical refill for water testing kit.

This product comes in handy for those wishing to frequently test their pool's cyanuric acid (CYA) level. Ideally you should not have to test it more than once or twice a year, and the little bottle of cyanuric acid reagent that comes in a typical HTH five-way test kit would be enough. However, I've noticed that my CYA level can fluctuate randomly and in a manner that simply does not make sense. CYA should only ever lower if you partially drain and refill the pool. Despite this fact my CYA levels have mysteriously dropped, overnight in at least one case, and left my shock treatment of chlorine useless. So now I check the CYA levels fairly frequently and always right before adding a large amount of chlorine. This product is super handy and I would highly recommend for anyone wanting to check CYA levels frequently. I pour a small amount into a cup and then use the little dropper bottle that comes in a HTH kit to draw up the reagent into that little bottle and then conduct the test by dropping the reagent into the test bottle that way. Cheers!

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.
