I was on a budget and picked up Tetra Advanced Filtration 20-40, along with a box of extra cartridges. I'm still a newbie and thought I was doing great LOL, then I found out that buy completely changing the filter cartridge you get rid of the bacteria. So I cut into the floss and dumped the old carbon out and put in fresh stuff from a new cartridge ( i figured it would work )
I can't afford one of the great filter systems yet so am doing the best with what I got, learn as you go I guess.
