So I know I'm not supposed to change my filter very often, but at some point I'm gonna have to change it. How often is good and do I need to do anything special to prep the new filter? I'm terrified of losing the biological filter when I do a change.
My tank has been running for just over 3 months and I've not changed the filters yet. I have a 29 gallon with a penguin 350 dual bio wheel filter.
