Works great, good price

Great product

Very good price

I have used 6 gallons of this over the past 2 days,in our 18,000 gallon pool and it is not registering any free chlorine. I have shocked it with 3.5 pounds of shock and still not registering (also from Sams) very frustrating) its not exceedingly hot and there isnt algae. Won't buy again.

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.

Great to find a 3 pack and at a great price. We needed to super chlorinate the pool so we got two boxes , put it all in at night so it won’t burn off in the heat/sun, by morning the pool is sparkling! Great find!

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

It’s a dollar more expensive than at Walmart for the same exact product
