Gel bacteria balls that contain millions of beneficial freshwater bacteria to help seed aquarium/pond filter media. The gel balls dissolve slowly in the filtration system and keep the water clear and healthy, which provides a stable environment for aquatic life.


A minimum of one ball should be added per 25 litres of aquarium water, to a normally stocked tank/pond, highly stocked systems will require more.


The balls can be replaced once they have fully dissolved, ideally during regular filter maintenance.
