So I was looking over this website, the creators of the Skippy Filter. Everything looks cool, till you get to the part where they say you should NEVER clean the filter. Even in winter. Does that make sense? I understand that if you clean the filter you're likely to lose a bit of the beneficial bacteria, but all filters need cleaning eventually, right?
