When chlorine doesn't cut the mustard ;-)

I use this once or twice a year to bring my pool back from the brink when regular chlorination isn't getting the job done. Works every time - just follow the directions and be sure to brush and super chlorinate after adding yellow treat.

Very pleased to find Yard & Pool, the best price online and free shipping over $100. I'm a happy customer!

Great Product that works.

The new formula does boost and also leaves a good chlorine level in the pool. I'm very satisfied with this product. Just follow the directions for great results.

Really Works

I used this regularly when I was a pool man. No longer in that business but the best product for yellow and only takes a capfull or two.

Marco F.
It does work to Zap Algae

Used as directed, clean filter, brush pool, add two capfuls for 20,000 pool. then shock with chlorine. It did knock down my algae problem. The 2 lb. cannister is three treatments for my pool. The Bromide and Chloring do a double whammy and kill algae in the pool and filter. Brush again.
I wish I could purchase a 10 or 20 pound size.
