fluval edge: base and carbon filter questions
Just received my Fluval Edge today. I was surprised how filmsy the base feels. I thought it would've been a sold piece but it was just a thin plastic shell and there were no ribs for any strength reinforcement. Do people have any problem/concern about it? When I press against the part deflects a bit, so I am kind of surprise that it can support 70+ lbs and afraid that one day the plastic will crack or something.
On a different question, what do people think about the carbon filter that came with it? In my old 93 gal tank, I never used carbon filter because I read that it was only a very temporary filtration and if you use it long enough, the toxic will re-release back to the tank. So I've only used mech and chem filtration and actually thinking of putting extra ceramic balls in place of it. Any opinions?
