Sol, I think I have the same tank as u do!! Is that a Tropiquarium 68 from Hagen? I have to add an air bubble wall along the back of the tank because food flakes can get trapped easily just at the corner where the filter is!
Other than that, I think it's doing a good job coz it holds more beneficial bacteria in the "dry" chamber. So I don't have to worry of killing the bacteria when rinsing the filter foam etc.
However, it's quite difficult to take out the "dry" chamber unit as there'll be some brown algae growing at the bottom. Taking out filter foam etc is easy tho.
KH, here I can't find anywhere selling Biolife filter alone, so has to buy as a kit. As for the stat:
output without air: 93 g/h
Output with air: 90 g/h
Biological water input: 0.4 - 0.55 g/m
Actually I have no idea what these means, just copied from the manual
