First time I have ever heard to NEVER change a filter....
Also Alot of those cheap filter pads have junk carbon in them that will sometimes leach phosphates. Just a lil fyi from my experience. I took my HOB
filter off and added a sponge in my sump in the baffles and use filter pad material on top. I change that every few days when it gets gross. that way my BB stays in the sponge and the gross stuff is changed out when I switch the filter padding
