4 Stage Filtration

A newly calibrated water path cycles through 4 complete filtration stages to optimize cleaning performance.
All media included.

Pre-Filter Stage

Chemical Stage

Biological Stage

Mechanical Stage

CycleGuard

CycleGuard maintains your aquarium’s biological balance and prevents nitrogen cycle disruptions. By allowing 1 of the 3 media inserts to be changed at a time, bacteria levels remain stable, supporting continuous and effective biological filtration without harmful fluctuations.

Patented Refiltration System

This unique feature permits flow rate adjustment without compromising filtration efficiency. When flow is reduced, the system will process up to 50% of the water several times within the chamber, ensuring a cleaner and healthier aquarium with exceptionally clear water.

Add-On Surface Skimmer

Compatible with both Fluval AC and AquaClear filter generations.
