Evolution Aqua Pure Filter Start Gel 1L

Evolution Aqua PURE+ Filter Start Gel is a live, concentrated bacteria culture for use in new pond filters. The gel based solution will adhere to the filter media, allowing the nitrifying bacteria it contains to colonise your filter fast . Once the filter media has been coated with the PURE+ Filter Start Gel, the beneficial bacteria within the gel will speed up the maturation of your filter media, while helping to convert ammonia and nitrite, resulting in less stressed fish. PURE+ Filter Start Gel is available in 1 Litre and 2.5 Litre sizes.
