I've heard some advice before on changing of filters. I've heard more than once that you should NEVER change the filter, because the bacteria are so good for your tank. I've also heard that you should rinse it a bit in water and put it back if it needs it.
I added a new filter to mine last night, but left the old one in (my filter takes up to two cartridges). Is this the right move?
