Why we love it

The filter design allows for maximum oxygenation and has high surface area foams for exceptional biological filtration.

The filter has different zones for different types of beneficial bacteria, which increases the conversion of harmful ammonia.

The built in cleaning indicator notifies you when the filter needs cleaned and the water temperature display tells you the water temperature.
