Compatibility, Size and Fit
The main fit check is the aquarium size, with a stated recommendation of 20 to 60L. The unit is described as an internal filter, so it is intended to sit inside the tank rather than outside it.
If you need a different tank size range or a different style of filtration, compare those requirements before choosing this model.
