Yeah I was so used to having to wash out my filter on my 55 that when I got newer similar filters that I didn't think about how much they changed within 7 years of when I first started. Lol won't make the same mistake again that's for certain, technically can't anyways since that 7 year old filter died out the next year.Ouch! That sounds like it sucked. I did the same thing when I first got into the hobby. I bought a canister filter without knowing how filters worked just because it was big, so it must be better. When it got dirty I replaced ALL the media. I didn’t lose anything, but the new cycle must of stressed the hell out of them cuz I had an ich outbreak shortly after.
