Works great, good price

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!

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

Not very strong, doesn’t make much difference to chlorine levels

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