Questions & Answers

What is the maximum aquarium rim thickness this filter can fit on?

The maximum aquarium rim size for AC20, AC30, AC50 and AC70 filters is 0.9″ / 2.4 cm. In the case of the AC110, it is 1.4″ / 3.6 cm.

How does water flow through an AC Series filter?

Water enters the filter via the intake tubes and travels to the bottom of the filter case. It then passes through the Bio-Foam, Carbon and BIOMAX before returning to the aquarium. When the flow control lever is set to its minimum position, up to 50% of the water is recirculated for slower but more thorough filtration.

What is the minimum aquarium water level required for AC Series filters to work properly?

For AC20, AC30 and AC50 filters, the water level should be no more than 5/8″ / 16 mm from the bottom of the filter output. For AC70 and AC110 filters, the water level should be no more than 1.5″ / 38 mm from the bottom of the filter output.
