HTH 3-inch Chlorine Tablets Advanced — Tablets (Form), 25 lb — Chlorinating tablets (pool chemical type) to sanitize pool water

I use this every summer in my pool. Dissolves slowly over a weeks time. Helps keep water sanitized and clear. Low chlorine odor. The cost of these has increased significantly over the past few years.

I've been using the HTH 3-inch Advanced Chlorine Tablets 5 lb Bucket for a few years now, and they've been consistently reliable. They do a great job keeping my pool water clean, clear, and well-balanced without a lot of extra effort. What I like most is how slowly they dissolve. I can drop them in the floater or chlorinator and not have to worry about constantly checking or adding more every day. They maintain a steady chlorine level and really help prevent algae, even during the hotter months. Over the years, I've found them to be a dependable, no-hassle option for regular pool maintenance. I also like that they combine sanitizing and algae control, which saves time and keeps things simple. The only small downside is that occasionally you'll get a few broken tabs or some chlorine dust in the bucket, but it hasn't affected performance for me. Overall, after using these for years, I can confidently say they're a solid, go-to product if you want something effective and easy to use.
