Pump output, filter circulation and maximum flow are measured in different ways. Your filter will move less water than the box says once media and hoses are in. Measure it with the flow calculator.
Before choosing this model
- Measure cabinet height and hose route.
- Compare circulation (121 GPH), not pump output (206 GPH), across filters.
