WaterMom makes a good point. The bleach sold by WalMart & the Chlorox at Sam's Club is 6% as is the bleach sold by DollarTree. The bleach sold by Dollar General & Family Dollar is 5.25%. I have to say that I was skeptical at first that using bleach would actually work but after giving it a try I am completely sold. It completely killed off the algae and turned my pool water sparkling clear and blue.
