2 Litre Gel Filter Starter Balls


2 litre polymer gel filter starter balls
Gel filter balls are the most efficient way to seed a new filter with beneficial bacteria as they dissolve slowly and release a measured dose of live bacteria into the filter. Simply add to the filter media after filter maintenance or when adding new media.
Use a minimum of 1 ball per 20 litres to seed new filters. You cannot overdose with this water treatment.

Please note the filter starter balls contain freshwater bacteria. If you have a marine tank you will need the Pure Reef Balance to set up the filter - also available from this site.
