  • Easy Pool Care With Reliable Results
Size: 4lb
Maintaining a pool can sometimes feel overwhelming, but this chlorine stabilizer from Clorox has made the job much easier for me. The product does exactly what it claims. It helps chlorine last longer which means I am not constantly adding tablets or shocking the water as often. Once mixed in, it keeps the water balanced for weeks and I have noticed a real difference in how steady my chlorine levels stay. One thing I appreciate is how straightforward it is to use. The instructions are clear and the granules dissolve well when added slowly to warm water before pouring into the skimmer. It does take a little patience because stabilizer is not instant, but once it is in the water and circulated properly, it delivers consistent results. Compared to other brands I have tried, this stabilizer seems more effective at maintaining chlorine levels even during hot summer weeks when the sun usually burns chlorine away quickly. I also feel like I am saving money on chlorine products because they are lasting much longer. Pros: reliable performance, clear directions, noticeable improvement in chlorine efficiency, and trusted Clorox quality. Cons: it can take a full day or two for the stabilizer to fully dissolve so you need to plan ahead but that is expected with any stabilizer. Overall this is a must have for pool owners who want less hassle and clearer water. It has become part of my regular pool maintenance routine and I highly recommend it. ... show more

  • Worth the cost and works as intended
Size: 4lb
I have a 36,000 gallon pool and need about 8-10lbs of stabilizer a year. I used to buy it from my local pool store because I like to give them the business so they stay in business. Finally though, decided to buy it online because it’s about half the cost. The only complaint I have is that it takes so long to dissolve (seems to be all brands). What I do is put about 3 lbs in a knee high stocking, tie the end and hang it in front of a return jet. After about 3 hours, it softens up and you can squeeze the stocking (keeping it in front of the jet) and it readily dissolves. ... show more

  • Great quality
Size: 4lb
I recently got a pool stabilizer from Amazon, and it's been a game-changer for my pool. It really helps keep the chlorine levels steady, so I don't have to mess with the chemicals as often. The water stays clear and nice, making swimming much more enjoyable. The product info on Amazon was spot-on, with easy-to-follow instructions. Plus, the reviews from other buyers were super helpful in deciding to go for it. The price was pretty fair for what it does, and it arrived quickly and in good shape. Overall, I'd definitely recommend this pool stabilizer to anyone looking to keep their pool in great condition with less hassle. ... show more

  • Cyuranic acid by a trusted name - works great
Size: 4lb
Great chlorine stabilizer and a great price. Delivered fast, dissolves quickly, and helps keep the water chemistry correct. Easy to put into pool, just open and pour SLOWLY into skimmer. That prevents a big clog in the pipes or skimmer basket. Like sunblock for your chlorine. Good stuff.

  • Great way to raise CY
Size: 4lb
This is a great way to raise the CY level in your pool. I tend to run about a 50 CY and keep my free chlorine level at about 7.5-10% of that level. This keeps the sun from burning off chlorine as fast and you can either save money by adding less chlorine or turning your salt water chlorinator down. Works as expected by just dumping it in your filter basket and it's cheaper than the pool store. ... show more
