Activex colonises pond filtration systems with all the essential strains of bacteria required for the part of the nitrogen cycle that Koi keepers rely on to neutralise ammonia and nitrite
Introduce 10ml of Activex per cubic foot of biological filter. There is no need to measure the filter system precisely and you need only feed the product into the biological part of the filter not the mechanical area.
In a mature pond use Activex occasionally to boost the filter performance particularly after any chemicals have been used which may affect the biology in the filter, or after heavy feeding during summer. In a new pond allow a few days between each application of Activex as the filter establishes and test water frequently throughout the colonisation process first for ammonia and then for nitrite.
