Product Information

Activex - Live Bacteria

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. Envirex is a live culture and differs from filter start products due to the gel it contains that forms a retention substrate in the filter for the bacteria to multiply on more quickly and effectively. The gel substrate is harmless and contains minerals to feed the bacteria.

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. The frequency for applications does not matter, every three days if you have a major problem establishing the filter with high readings or if you are coping follow the directions on the bottle which is only a guide, and with a natural product there are many ways to use it successfully.
