Product Summary

This blend of live bacteria and enzymes is specifically designed to improve water quality by reducing unwanted nutrients in your water. It clears out pond- or lake-bottom debris like leaves, grass clippings, dead and dying plants, excess food and other organic matter. These bottom-lying materials are referred to as the sludge layer and are responsible for bad odors and low oxygen levels. Each 5-lb. block treats up to 5 acre-feet of water. Non-chemical treatment is safe for fish, plants and other wildlife. U.S.A.

Features + Benefits

  • Increases clarity – Use pond boss® PRO The Block™ as part of a routine maintenance program to consistently keep water clear.
  • Promotes a healthy environment - The Block™ improves dissolved oxygen levels and reduces ammonia and nitrogen levels.
  • Breaks down sludge - Uses a blend of live beneficial bacteria and enzymes to break down the sludge layer and to compete for the food source of unwanted bacteria in the water stopping problems before they start.
  • Designed to reduce sludge
  • 5-lb. block treats up to 5 acre-feet of water -- bacteria is released throughout the entire lake or pond, but the majority of sludge-reduction does occur in closer proximity to the block application site

  • The Block™ can be used in natural lakes, man-made lakes, large ponds, golf courses and other bodies of water when used as directed.
  • Environmentally safe: The Block™ is safe for plants, fish and wildlife.
  • 5 lb. block treats up to 5 acre-feet of water (1.6 million gallons). Treat every 60 days for best results.
