How the Nexus 320+ Works

Pond water enters the inner vortex chamber where heavier solids settle. It then passes through the Eazy with a static bed of K1 Micro for mechanical filtration. The clarified water flows to the outer chamber, where the K+ Moving Bed provides high-efficiency biological treatment. Beneficial bacteria convert ammonia and nitrite into nitrate

Is the Nexus 320+ pump-fed or gravity-fed? It can be installed either pump-fed or gravity-fed. Do I need extra media? The unit includes 100L of K+ Media. You can expand up to 300L for high stocking density or future growth. How often do I clean it? Use the Eazy cleaning cycle as needed based on fish load and feeding. Many users pair with the Nexus Automatic Cleaning System for hands-off maintenance. What pump size is recommended? Target 8,000 to 11,000 LPH for optimal turnover, ensuring actual flow after head loss is within the 11,000 LPH recommended rate. Does it include a UV clarifier? No. Add a compatible in-line UV such as TMC Pro Clear or Oase Bitron sized to pond volume and flow. Important
