I currently use this filter on my heavily planted 167 gallon tank but that's pushin it. I think a 120 gallon aquarium is a good cap for this one, you are still gonna want some additional flow.
Biomaster filters are super easy to clean due to the quick releasing pre-filter feature. You dont have to actually open up the filter to clean this compartment.
