PURE+ Filter Start Gel is a live, concentrated bacteria culture for use in pond filters. The gel based solution will adhere to your filter media. PURE+ Filter Start Gel contains friendly, nitrifying bacteria. Once the media has been coated with the gel, the bacteria and enzymes get to work converting toxic ammonia and nitrite and maturing your new pond filter.

The PURE+ Filter Start Gel is well suited for use in bead filters, particularly Evolution Aqua’s K1 Micro Bead filters to speed up maturation from day one - but is equally effective when spread on Japanese matting, conventional beads, K1, filter foams and all other types of filter media.
