Built to provide years of trouble free service, the Stainless Steel NishikigoiRDF-NGRDF30SS is designed for serious koi pond owners looking for reliable, high-performance mechanical filtration.
The NishikigoiRDF Drum Filter automatically removes suspended waste before it can affect water quality, delivering crystal-clear water, healthier koi, and dramatically reduced maintenance. Built for performance and engineered to last, it’s the professional’s choice for serious koi ponds.
The NishikigoiRDF units remove solids down to 75 microns. What does this mean? It means the BioMechanical Filter that you use such as one of the AlphaONE or AlphaNANO filters can perform the way they want to perform and that is with out solids clogging the filter. This lets the filter and bacteria do what it really wants to do and that is handle the solubles in the water instead of solids. Solids lowers the efficiency of the filter.
The NGRDF30SS is perfect for larger ponds. Combine with one of the Wakimizu Bakki Showers for one of the perfect Koi Pond set ups.
A lot of people would like an RDF but they are scared to take the leap. Now you don't need to be scared, GC Tek is here to help with your clear, healthy water dream.
