I just opened our Florida pool for the summer season. I was going to stop by the pool store and pic up some chlorine on the way home but I stopped at Sam's for some other stuff and saw this. Since Chlorine degrades with time, and sometimes chlorine from pool stores that store it in big tanks outside in the sun is weak. I though I would try this since it is sealed up the environment it is stored in is bound to be better. I'm happy to say this product worked very well. The standard dose I usually use gives superior results compared to what I have been using. Its also nicer to store as the bottles are sealed and don't give of gas like pool store refillable jugs. Keep it in a cool dark place.

Price Price and Price ! Chlorine is Chlorine ! Great value

Very good price

Perfect. So thankful the club has this in stock! Wish is was 12.5% but happy with 10%

This product could be better. It’s ok to maintain the pool chlorinated during cold days but useless in this Texas heat.

I followed instructions exactly, measuring the amount needed per gallons of water in pool. I have used the product three times since purchasing. I notice there is algae after 3 days it was poured into pool, so I tested the water with my chemical test kit, it showed zero chlorine. Well that seems unbelievable but I dosed the pool again and added several extra ounces. In 3 days, same thing, test is negative for chlorine. This product doesn't work. No free chlorine or total chlorine registered. Total Fail. two stars because the liquid formula was a great idea and easy to measure and apply.
