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 19620 and the AC110 size.
- Measure the free length of rim, the gap behind the tank and the space above the lid before buying.
What Fluval doesn’t publish
- Fluval gives the AC110 its own rim-thickness limit, separate from the 0.9 inches of the smaller AC filters, and we have not read it. Check the AC110 manual before buying for a tank with a thick rim.
