Results in 24 Hours
Would RecommendWe started working on cleaning our "swamp" and had literally tried everything. Our 15k size pool was was in such a bad way that you couldn't even see the bottom of the shallow end. We barely met the requirements on the label for PH and free chlorine. We started by adding our regular chlorine tabs, setting the pump to filter, added about 20 oz of the product along the edges of the pool and left the pump on filter for 24 hours. Finally!

Cleans up the pool just fine

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.
