Finally the black algae is gone
Would RecommendI've been fighting black algae all summer. I finally changed both the algaecide and the shock brands and it's gone. Not sure which helped the most, but after an entire summer it's gone in one treatment of both. I don't care which worked I'm just thrilled. And maybe it was the combo of both.

Horrible weak solution
Would Not RecommendThis product is very expensive. It is also very ineffective. Do not waste your money. Clorox brand pool product does not equal the quality you might expect. A very poor value.
