Microbe Lift MLCBSE500 Barley Straw Concentrated Extract Pond Conditioner

  • Fast-acting
  • Easy to use
  • Consists of natural ingredients
  • Non-hazardous to fish, plants, pets, wildlife, etc.
  • Made in USA

Long thought to be an old wives’ tale, university studies have proven two mechanisms by which barley functions to help prevent excessive algae growth. The first is the release of humic acids as the barley decomposes. This can take up to six weeks with barley bales. Pellets will release these compounds within approximately one week since the barley has been partly broken down during processing. But the Barley extracts release these compounds almost immediately. The humic substances released are large molecules with numerous binding sites that tie-up nutrients, primarily nitrogen and phosphorous compounds, that are essential for synthesis of algal protein, and thus required for its growth. Removing these macronutrients from the water column essentially “starves” the algae out.
