I purchased these in a 2 container set as I figured the size of my pool is about what it would need plus a little extra if I needed to retreat any spots I may miss the first time. I treated the black algae as stated on the containers and it worked great. No more black algae spots in the pool. I will definitely use this again if the algae returns. Thanks for a great product.
