Should you change filters?

[VulcanNinja]

I've read conflicting advice on this because of the bacteria thing. I've had a whisper filter in my 10 gal for about 4 months now. I haven't replaced the filter, but just rinsed it in old tank water. It's worked pretty well, but now it's starting to overflow a bit. What should I do?

Well, you should buy a new sponge, just don't throw out the old one, let it hang in the tank for a bit (I know, this is the downside to hang on back filters, unless they have a gravel compartment) HTH
