We have been buying this product for years. We love it.

Great product at affordable price

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

Great product, keeps the poll clear and free of algae

This is a quality product for a good price. Delivery was poor.

Price was 75% lower than local pool store

Excellent product, priced reasonably

Great product works very good

Didn’t work- caused large amount of bubbles for days!

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