Aqua Chem Optimum Chlorinating Granules for Swimming Pools, 5-Pound

I love this product for our 18 ft intex pool. It has chorine as well as an algeaside that works. Says use daily, but in Texas summer heat and full sun the majority of the day, it stays balanced and chlorinated for at least two to three days. Hate trying to use multiple chemicals to balance and get the water chemistry just right, and with this I don't have to do that. Will never go back to individual chemicals because this does it all.

Works as stated and a better value!

Well priced and good product.

love it

Bought this for my hot tub. Works great!

Perfect for our smaller pop-up pool. Kept the pool clean all summer!

exactly as expected... thanks

Works as needed!
