The Pond Boss Pro The Block Pond Bacteria Treatment is a blend of live bacteria and enzymes specifically designed to improve water quality by reducing unwanted nutrients. Decaying nutrients such as leaves, grass clipping, dead plants, excess food and other organic material build at the bottom of the pond in what is commonly called the "sludge" layer of the pond. The sludge layer is most often responsible for undesirable odors and low oxygen levels. Regular use of Pond Boss PRO The Block will consume decaying organic material at the bottom of the pond and in the water column. Results may vary based on weather and use of other products.

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.

  • 5 lb. can treat up to 5 acre-feet of water (1.6 million gal.)
  • Increases water clarity
  • Controlled release that regulates efficiency
  • Significantly reduces noxious odors caused by hydrogen sulfide, dead plant material, and fish waste
  • Reduces ammonia and nitrogen levels
  • Dissolves away organic sludge
  • Improves dissolved oxygen levels
  • Effective over a wide range of pH conditions and water temperatures
  • Use in water temperature of 50° or higher

Confused

I am really confused about the safety of this product after reading some of the reviews. It's not safe to eat fish in the pond or consume cattle that drink from the pond but the ducks are safe. Please go through the reviews.

Misleading Description

Haven’t bought, will not buy. Advertising on purchasing page doesn’t say “Don’t eat Fish after treating pond” I found out in the comments!

The pond water was visibly clearer in a week. By the end of 2 weeks, I can see the fish swimming around!
