Ease Of Cleaning
As long as it works, use it. If not, don't worry too much about it.
Most high-quality products are designed so that they require cleaning to keep their performance up.
Always be sure that you can replace some of the filter media if you need to without having to replace all of it at once. If you do so, you may end up killing off some of the fish.
Substrates And Plants
A heavily planted aquarium, especially one with soil and gravel as substrate, is able to process nitrogen effectively making anaerobic filters less important for heavily stocked aquariums and aquarists who don't perform regular water changes.
If you're not already doing so, you should add some sort of substrate to your aquariums to help keep them from becoming too acidic. A good option would be to use a soil mix made up of equal parts peat moss and perlite (or any type of medium) and then adding some gravel or shells to provide structure. You could even add some live rock if you want.
