Has not killed the algae yet

Have used it for several years!

Been using this for several years. Very cost efficient and only need a few ounces for treatment.

Great product, keeps the poll clear and free of algae

Cleared up algae in a few days.

If you want a very sudsy pool, then this is for you. Takes several days for the suds to go away.

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

Excellent products and quality professional service

shipped fast. good price. works fast.

Price was 75% lower than local pool store
