I have been buying this for years. I keep at 3 part per million and shock on Monday nights after weekend swimming. Never had any problems.

When they delivered the item, they left on the curb not even close to my front door. luckily it wasn’t stolen.

i always bought this at 79.99. what happened?? i had to go back to my purchase history to make sure if i was mistaken about this.

Chlorine Tabs I haven't used one yet but was so glad to find them. I will be using today as I have ran out of what I had.

They do what they are supposed to and last longer than others. Insane how these doubled in price since last year.

Product works good, but is over 3 times the price it was just a few years ago. Way too expensive for what you are getting!

Great product!

Good value

It WORKS

Best value for the buck.
