How do I change out my filter without disrupting the good bacteria and throwing the tank into a cycle? The filter is filthy - I've never changed it or done anything to it. The color of my tank's water is milky - it hasn't been clear in weeks (I'm dealing with a separate algae issue, which I'm handling with AA help) Should I change out the pad and put a section of the old filter pad on top of the new filter pad? I'm concerned about the good bacteria. Please advise!
