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
- Confirm item 100106081 and available rear clearance.
- Budget for Large cartridges if using them as supplied.
What Aqueon doesn’t publish
- Aqueon doesn’t publish the flow rate or the watts. Don’t compare its flow or running cost with filters that do; read the watts on the pump’s label before you use the electricity cost calculator.
- Aqueon now sells the newer PRO QuietFlow in its place; the tank size here is from Aqueon’s own page for the LED PRO, as archived in October 2025. Check the box says item 100106081.
