Hey everyone, I question popped up into my head. Should I ever change my filter cartridge? I think not, but my family keeps insisting that I should change it. I keep telling them that all the good bacteria is on the filter media but they still think after a while it will get to clogged up and I would have to change it. Is this true?
Also, once a month I change the carbon in the filter cartridge and every week or so I swish the filter cartridge in old tank water. Of course, my family still doesn't think that is enough.
One more thing, they're actually only telling me I should change the filter cartridge once a year I'm telling them that I should never change it. Who's right?
