Item Information

The Pond Boss PRO The Block 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.

  • 5 lb. can treat up to 5 acre-feet of water (1.6 million gallons)
  • 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

Can you swim in the pond or lake if treated with product? If so, how long after treatment, should one wait before swimming? Can fish be consumed if this product has been utilized?

Asked by: Nece1016
The product has not been tested for recreational use or fish consumption. The manufacturer does not recommend either .

We have a 50 year old 16 acre lake, quite shallow all over. 3 ft on average to 8 in the middle mainly due to years of plant growth sludge, cattle, geese, ducks, hydrilla etc... so lots of sludge built up for years. Will this help reduce any of this?

Asked by: GTOsali1967
Yes, with regular use of the block, it 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.

I have a 2-3 acre pond, this is a 2 fold question, will this block work for getting rid of algea and lily pads that are above the water? and secondly if we choose to catch fish out of the pond and cook and eat them I'm assuming would NOT be ok?

Asked by: Stuckey
This product will not kill algae or lily pads on the surface. It is intended for the "sludge" at the bottom. You will need an algaecide for that task. We do not recommend eating the fish if this product is used.

I am confident we have less than 5 acre-feet of water. The block has been in the pond for 20 days with no change. Our pond is choked out with duck weed, has cat tails and a lot of muck. Should I bother throwing another block in it after 60 days?

No. The Block (5 lb) is safe for fish, plants, and animals. One 5 lb. block treats 5 acre-feet of water (1.6 million gallons). We hope this helps.

How many different strains of bacteria and enzymes r in the product? If I want to improve the sludge at the bottom of my lakefront out about 10 ft, would it work in my area if the rest of the lake isn't using it? R U affiliated with Texas Pond Boss?

Asked by: WaveAction
This product contains 4 strains of heterotrophic bacteria. This would help improve the sludge layer in the lake, but should be used across the whole lake. The pond boss brand is not the same as Texas Pond Boss. We hope this helps!
