Unmatched Flow Rate
RNR Advantage SS showers boast one of the highest cubic feet of water per second flow rates in the industry. This exceptional throughput allows for optimal contact time between water and biological media, enhancing biofiltration efficiency and oxygen transfer — two key factors in maintaining a healthy pond ecosystem.
