For optimal water quality, it’s commonly recommended to change 10% of the water volume in your pond or aquarium weekly. The Nexus Automatic system can be set to align with this guideline. Additionally, for the best performance, a turnover rate of every 2 to 3 hours is recommended. This ensures the total volume of the pond passes through the filter system within that time frame.
