Bactozym works to accelerate the development, or "maturation", of friendly bacteria within aquarium filters. This helps to prevent New Tank Syndrome, which commonly occurs in aquariums with new filters, or when the filter has been damaged. In new aquariums, the use of Bactozym allows the first fish to be added after 24 hrs.

How it Works

Bactozym has a unique two-way action which removes harmful waste and speeds up filter maturation. It stimulates the decomposition of uneaten fish food using naturally occurring enzymes, and it creates ideal conditions for the rapid development of filter bacteria. This helps to avoid the accumulation of harmful pollutants during the early stages of setting up your aquarium. Bactozym can also be used to reestablish filters that have been damaged.

How to Use

Add Bactozym to all new filters, and after cleaning established filters. For new aquariums, add 2 capsules per 100 litres (22 gallons) of aquarium water, placing the capsules directly into the filter. Repeat every 7 days. After cleaning the filter, add 1 capsule per 100 litres (22 gallons) of aquarium water.
