Excellent strength material and works well

Great product, keeps the poll clear and free of algae

Been using it for at least 8 years and it works if you follow the directions.

I drove about 50 miles to pick this up from a different Sam's Club since our area was sold out!

Not quite as effective as the 60% products but I haven't had any problems yet.

Worked great for pool..cleared the water

Great product works very good

Clears your pool right up!

Have used it for several years!

Always buy my chemicals fromSams
