  • Exceeded my expectations better than others I have purchaced
Size: 1.5 lb Bottle
HTH 42049 Swimming Pool Care 1" Chlorine Tabs have completely exceeded my expectations when it comes to maintaining my swimming pool water. These chlorine tabs are nothing short of remarkable, and I'm thrilled to share my positive experience. What sets these tabs apart is their slow-dissolving formula. Unlike cheaper brands I've tried in the past, these tabs dissolve gradually, providing a consistent and longer-lasting chlorinating effect. This slow-release feature not only ensures that my pool water stays sanitized for an extended period but also minimizes the frequency of application, making it incredibly convenient for pool maintenance. The effectiveness of these chlorine tabs is truly impressive. I've noticed a significant improvement in water clarity and overall pool hygiene since I started using the HTH 42049 tabs. They tackle algae and bacteria with efficiency, leaving my pool water crystal clear and inviting. The 1.5lb size is perfect for my needs, offering a sufficient quantity to last for an extended period. The packaging is sturdy and resealable, keeping the tabs fresh and ready for use. It's evident that HTH prioritizes quality in both their product and packaging. In comparison to cheaper alternatives, the HTH 42049 Swimming Pool Care 1" Chlorine Tabs have proven to be a wise investment. While they may cost a bit more upfront, the slow-dissolving feature and overall effectiveness make them a cost-effective choice in the long run. I appreciate the peace of mind that comes with knowing my pool is well-maintained with a reliable and high-quality product. If you're looking for chlorine tabs that dissolve slowly and work more effectively than cheaper brands, HTH 42049 is the way to go. I highly recommend these tabs to fellow pool owners who prioritize the health and clarity of their pool water. Five stars for a product that delivers on its promises! ... show more

  • Efficient and Reliable Chlorine Tabs for My Spa
Size: 1.5 lb Bottle
These chlorine tabs have been a game-changer for my Coleman Saluspa! With the use I have in my spa, I find that I only go through about two tablets per week, making them incredibly efficient and cost-effective. The tabs dissolve easily and maintain the perfect chlorine level in my spa, ensuring clean and clear water for a relaxing soak. I appreciate the convenience of these tabs, as they eliminate the need for measuring and handling liquid chlorine. They are compact and easy to store, and the packaging keeps them fresh and intact. The tabs work seamlessly with my spa's filtration system, and I haven't experienced any issues or cloudy water since I started using them. Not only are these chlorine tabs effective, but they also offer great value for the price. They have become an essential part of my spa maintenance routine, and I highly recommend them to anyone looking for a reliable and hassle-free way to keep their spa water clean and sanitary. Overall, these chlorine tabs have exceeded my expectations and made spa maintenance a breeze. They are definitely a worthy investment for anyone with a spa or hot tub. ... show more

  • Small but powerful
Size: 1.5 lb Bottle
Tablets were super small in size please be aware of were you put or keep them around pets and kids. You get a good few months worth. Price was alright for the quality & quantity. Make sure when opening not to breath in it's a hard chemical and it's hard to breath if it is breathed in. Also keep in mind swimming with out eye goggles or eye protection will hurt and sting the eyes and please don't drink the water. It's chemicals. ... show more

  • Can use these for Fluidmaster Flush n' Sparkle toilet bowl cleaner
Size: 1.5 lb Bottle
Fluidmaster Flush n' Sparkle is a great product for keeping your toilet bowl sanitized -- it releases chlorine into the water with each flush, but without chlorinating the water in the tank which can cause degradation of seals and other parts. Unfortunately, Fluidmaster charges a hefty price for every single refill (needed about every 6 weeks in my experience). Instead, you can refill the Fluidmaster cylinder with 3 of these tablets at a fraction of their cost. You just have to pry the bottom cap off of the cylinder, which is admittedly difficult but worth the effort. I use a screwdriver tip to pry and push the cap off. I removed the foam rubber spacer that's in the Fluidmaster cylinder (not sure what its purpose is), and the cleaning system works just great. ... show more
