Technical specifications

Bacterius™ 5B concentrated bacteria dry formulation consists of billions of microbial cultures made up of beneficial natural bacterial strains specifically chosen to reduce dissolved organic carbon and organic sediments consisting of both cellulose and lignin components of dead and decaying algae and vegetation.

String algae choking a pond, in need of concentrated bacteria!Use Bacterius™ 5B concentrated bacteria in your pond or lake for severe or persistent algae blooms, deep organic, nutrient rich sediment and unpleasant odour problems. The concentrated bacteria formulation in Bacterius™ 5B acts quickly, hastening the process of organic decomposition when applied regularly and in the presence of lake bottom aeration. Even for instances when unwanted aquatic weeds such as Eurasian milfoil are present and worsening, Bacterius™ 5B is the answer. All beneficial bacteria are more efficient in the presence of lake bottom aeration.

With 5 billion active cells per gram, the pure and pathogen-free cultures in Bacterius™ 5B are the strongest pond & lake bacteria available. No need for premixing or messy dilution, 5B is packaged in pre-measured, half pound water-soluble packets, to allow for easy dosing. Simply toss in the appropriate number of pouches into the pond or at the lake shoreline, as the pouches dissolve, they release the beneficial bacteria into the water column, where they sink down and begin the process of consuming the nutrient rich muck.

Bacterius™ 5B is an effective treatment to remove organic matter that causes water clarity problems. Bacterius™ 5B reduces the odor and murky water associated with various types of accumulated organic wastes in lakes and ponds. This premium blend of natural bacterial cultures is an extra-strength pure bacterial mixture for accelerated treatment. This bacterial mixture provides an aggressive yet safe way to combat algae without the use of harsh chemicals.

Bacterius™ 5B improves overall water clarity and reduces odors, naturally enhancing the entire aquatic environment with no chemicals. When even the frogs won’t come to your pond, perhaps it’s time for Bacterius™ 5B!
