I imagine I'm over thinking this one,but with all the talk about filters and bacteria I figured I'd ask.
The tank is two and 1/2 mothes old and fully cycled for the last four weeks.I have never changed the filter.
But now its starting to fall apart so I ask:
Just swap them out?Put them both in for a while (if they fit)?How do you guys do it?
Its a top fin 30 HOB
.It uses the little white charcoal filled replacment bags.
