This calculator is designed to match your pond with the most efficient aeration system. By entering your pond’s surface area, depth, the tool will analyse the data and recommend the optimal Oxybox model to ensure proper oxygen distribution and water quality management.
When you see the airflow results above, remember that diffusers don’t just move air, they move water. Fine-bubble diffusers typically entrain (lift and circulate) 15–20 times the air flow rate in pond water, depending on depth and bubble size.
For example, at 6 ft depth with ~45 L/min of air flow (one diffuser outlet):
This means even with modest airflow, your Oxybox system is circulating a significant volume of pond water, improving oxygenation and destratification far beyond the air flow number shown in the calculator.
