Viresco Koi Algae Treatment

Write the first review


Viresco Koi is a totally natural solution to blanket weed in your garden pond water. Not only combating blanket weed, Viresco Koi also contains a sludge remover. A non-chemical, totally biological treatment. 

It is a micro-organism product that has a number of benefits when used in your pond:

  • Suppresses blanket weed and algae bloom by removing the nutrients on which they feed. It does this by removing nitrate from your pond water down to zero. When it reaches zero, blanketweed and algae blooms will die from starvation.
  • Digests the organic wastes found on the bottom and side of your pond which can be detrimental to the health of your fish.Improves the digestion and general health of your fish by improving food uptake and reducing disease.
  • Reduces the phosphate levels in your pond water.

Viresco Koi has a long shelf life.
