Tetra Bactozym speeds up biological activity in the aquarium. Organic colloids naturally cover filter material and all surfaces with an invisible film to promote the colonisation of beneficial filter bacteria. This means that the first stock of fish can be added just 24 hours after setting up a new aquarium. Both water changes and filter maintenance can be performed without any serious loss of bioactivity.

Dosage: Use the product when setting up a new aquarium, with every filter change or filter maintenance, after every partial water change and after treating the aquarium with medication.
