Love this Product

I am on my 3rd year of using this product! Although my pool is small, it is not covered and I get a lot of pollen, dirt, and leaf debrie I have not once had an algae problem because this product works! It keeps algae away, PH balance is good, very good product.

My favorite tablets have all you need.

This is my favorite tablet for my huge swimming pool. The water improves the longer you use the tablet. It makes taking care of a pool a breeze! No clouding.

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.
