Results in 24 Hours

We 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!

Works well.

we have used this chemical to help eliminate and as maintenance following an outbreak of algae - no more problems - this works well to maintain our algae free pool

Good bye Algae

The first time I used it there was algae in the pool and it cleared it up now I stay pro active and use it regularly in the Sumner as preventative.

Excellent product

We've been using this product for a couple of years now and we do not have any issues with algae

Finally the black algae is gone

I'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.
