The only thing that would make it better, is if it was a pack of 4! Good processing date on the box too!!!... Very important that it isn’t old... Otherwise you would be just poring expensive "water" diluted by shelf life. This is the 10% version we purchased. Knocked an algae bloom righ out of our pool.

We heard a hack to try with pool chlorine and using it to clean your pressure treated wood fence. You mix it 50/50 with water and spray it on your fence and it makes it look like new. Highly recommend trying it since it doesn’t kill grass or shrubs.

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.

Happy to recommend this 3-pack pool essentials product. This were very easy to use and works great! Very competitively priced.

Price Price and Price ! Chlorine is Chlorine ! Great value

Excellent, it shocked my pool, clear and clean

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

I received the order as expected but when we opened the packaging we noticed a strong bleach smell then found the jugs had been leaking in the original box.

Only 10 vs 12.5 potency at menards or

Could not tell the Chlorinating Liquid did anything, even after doubling up on the amount per the instructions.
