I'm sorry I didn't mean my bio media....I meant just the filter flosses and the foam pads for my wet/dry and fx5...Bio media I've never replaced
Again I'm not argueing that the ehiem is nothing compared to the FX5 like I said I do believe it is a better filter so I hope the ehiem pro owners don't take any offense; but the difference in bio filterations is not worth another 2bills. Like I mentioned for less than 4 bills I have the wet/dry an fx5 and ended up with a much better filteration system anyway this is why i went that route instead.....
