HTH 22007 Ultimate Mineral Brilliance Chlorinating Granules for Swimming Pools, 5 lbs

This product keeps the hot tub clean. To use, you just pour the recommended amount on the filter. That allows it to spread easily throughout the water. I have also just poured in in the water and that worked too. I highly recommend this product.

This product is wonderful! Keeps my pool looking clear with no work and other chemicals work great with it also. This is my goto product with easy to use opening helps keep my pool clean.

I thought this product was fine until I drained my swim spa and found tons of tiny blue specks. Will not finish and can't imagine what that may have done to my spa motor and parts. Stay away from this product in my opinion.

It is the best all around pool product for my above ground pool to keep the water clear and clean.

Just got through filling up the pool and of course with well water it was green! Worked on it about a week with various internet solutions (come on everything on the internet is the truth LOL) to no avail, notta, nothing, still green. Started researching again on the almighty world web and came across this on utuber and decided to give it a try. WOW! It is a 24' 52" above ground pool and I threw a couple of cap fulls in it and wala within two hours crystal clear.

This works quick and great! It doesn’t dissolve as well as I thought it would but it’s still worked perfectly for us. Took the slight algae smell away and clears our pool right up every time. The product settled quite a bit and I reached out to the seller but never heard back (could be user error on my part)

Worked better than the liquid pool shock for us. Great product!

This stuff works great. I found it at Walmart. I just use this and a little conditioner every now and then. The problem with this product is actually getting a hold of it. If you can get it for $20, it’s worth it, but not for $35-$45 for the same size. It is my favorite pool product.
