The New Rena OEM mini-pond and fountain filter kit includes a small and very versatile submersible filter box and a Rena OEM 350 gal pump for ponds up to 750 gallons. Installation is so easy and takes less than 30 minutes to install. It works for mini-ponds, patio ponds, fountain basins and preformed decorative ponds. It functions both as a pump pre-filter and biological/mechanical filter for smaller ponds with fish and plants.
The compact Rena RO1300F (350gph) is the ideal pump for this filter. The water coming into the filter passes through two-layers of foam, coarse and fine, and then enters the bottom area of the filter that contains 10 large 2" bio-balls which host a very large bacterial colony that breaks down fish and other organic waste from plants into harmless nitrate. The nitrate can be removed from the pond during water changes or used by the plants for extra fertilization. Nitrate water also make a great fertilizer for any and all plants.
