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

Great Maintenance Product

5 years ago
I had the worst pond ever, overgrown, tons of weeds, and muck piles. I hired a pond firm to help safely kill off the weeds. This produced more muck which was expected, but my maintenance company said I needed to dig out the 7 acre pond. I chose to treat the pond with Pond Boss blocks and Muck Away tablets thrown on the muck piles. Over two years my pond maintenance company is in shock how clean my pond. I had islands of muck, now it’s clean and the fish are thriving. I added 3 aeration diffusers which I cobbled together for cheap. I wish I could post pictures, my wife can’t believe the changes. Use the blocks in your maintenance program with aeration for best results - you won’t be sorry.

Confused

2 years ago
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!

Clearer Water

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