## Description

HTH Chlorinating Tabs are a simple, convenient way to keep your pool water clean and clear. Simply place tab(s) into the skimmer basket, floater, or feeder to sanitize and protect your pool water from algae and bacteria. They are sun protected and designed to dissolve slowly, giving your pool a steady source of available chlorine for up to one week. HTH Chlorinating Tabs are great for all pool types, including small pools, pop-up and above-ground pools, vinyl-lined pools as well as saltwater systems. Available in 1" and 3" tabs. How To Use: Follow the on-pack instructions to place tab(s) in your swimming pool feeder, floater, or skimmer. The number of tabs you use depends on your pool size.

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!
Review: Works with Fluidmaster Flush & Sparkle. - 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.

### ⭐⭐⭐⭐⭐ Can use these for Fluidmaster Flush n' Sparkle toilet bowl cleaner
*by R***N on April 8, 2025*

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.
