HTH Pool Care 1" Chlorine Tabs, Swimming Pool Chlorinating Sanitizer, Kills Algae and Bacteria, 1.5 lbs.

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!

Works with Fluidmaster Flush & Sparkle. If you're tired of spending so much money on refills for your fluidmaster toilet cleaning system then use these tablets instead of replacing the entire cartridge. The bottom cap pops off and 4 of these tablets fit perfectly inside. It does have a chlorine odor but it's not too strong and to be honest, that's the only way of knowing it's working without taking off the tank lid. I haven't used this long enough to see how long it lasts but it's certainly way cheaper than new cartridges. You may have to replace the cartrige o-ring or at least lube it so that it last longer.

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.

Work well in my hot tub. I put 1 in a floating automated dispenser, and set it to the lowest setting. Each tab lasts a few days.

These 1-inch chlorine tablets are a great choice for small pools, spas, or floaters. Don’t let the size fool you—these tabs pack a punch. They dissolve slowly and evenly, keeping chlorine levels steady without the hassle of constantly checking and adjusting. Perfect for above-ground pools, kiddie pools, or hot tubs where 3” tablets would be overkill. They help keep water clear, fight algae, and kill bacteria just like the bigger tabs, but give you more control over dosing in smaller volumes of water. They come individually wrapped (depending on the brand), which makes storage easier and less messy. Just make sure to keep them in a sealed container, since they can crumble a bit if exposed to moisture.
