AlgaphiteBio is a natural formulation of bacteria for the prevention and treatment of blanketweed and other aquatic algae in ponds and lakes.

Dense mats of algae and blanketweed reduce the visual appeal of inland aquatic waterbodies such as ponds and lakes and can have a negative impact on recreational activities such as fishing, swimming and boating. In addition, blanketweed and other aquatic algae can smother other aquatic plants and reduce oxygen levels in the water, leading to problems for aquatic plants, fish and other aquatic creatures.


High levels of nutrients in the water can encourage this excessive build up of blanketweed and other aquatic algae. To combat this, AlgaphiteBio contains six species of naturally occurring bacteria which feed directly on the phosphates and nitrates in the water. Starting applications of AlgaphiteBio early in the season, reduces the amount of nutrients in the water so that blanketweed and algae are not able to proliferate.

AlgaphiteBio is available in two easy to use formulations:

  • A liquid, packaged in an easy to use dosing bottle. Simply squeeze the sides of the bottle to fill the dosing chamber with the required amount of liquid (10 ml treats 250 l water), dilute in water and distribute over the surface of the pond or lake.
  • For larger bodies of water, AlgaphiteBio is also available as a granule packaged in biodegradable sachets. Simply calculate how many sachets are required and distribute over the waters surface.
