How often do you make changes in a filter 2.5?
Still twice weekly, one 50% and one 100% ?

How about a full water change every week with a 2.5? Is there a con to that?
You are never supposed to do a 100% water change. It gets rid of all your beneficial bacteria and basically ruins your cycle. Plus it stresses the fish too much.
