I usually say a weekly partial change because I know it isn't going to get done that often...however if I keep that in mind, then it doesn't get so far behind. In reality, a partial cleaning happens every week and half to two weeks. I have a 75 gallon tank with two turts and an xp3 filter. That is what was recommended for me, and it's what has worked for me, so it's what I recommend as well. In my opinion, it is better than suggesting to do a partial water change every three weeks and then having done every four to five in reality.
Pick what works for you, but just remember a dirty tank is necessarily what you see!
