PURE+ Aquarium Filter Start Gel is a live, concentrated bacteria culture for use in new aquarium filters.

The gel based solution will stick to the filter media, allowing the nitrifying bacteria it contains to rapidly colonise your filter. Once the filter media has coated with the PURE+ Aquarium Filter Start Gel, the beneficial bacteria within the gel will speed up the maturation of your filter media, while helping to convert ammonia and nitrate, resulting in less stressed fish.
