if you have a eheim 2252 then you know what a great filter eheim make the 2252 is one great internal filter i have had one running 24/7 for over 12yrsberserker;2172817; said:I've had my FX5 running over a year now-had no problems but must admit the flow rate isn't the same as the hype it's given. I've been quite disappointed with the power from the outlets. I'm seriously considering saving to an Eheim Pro 3 mainly because of its superior biofiltration-I have a Eheim 2252 internal to take care of the mechanical side.
I think this whole debate really is apples vs. oranges; to me they're two completely differently designed filters for two different purposes i.e. mechanical and bio filtration. You need to decide as an individual what exactly you want your external to do more of.
Just curious, if your saving for a pro 3, why not run both?berserker;2172817; said:I've had my FX5 running over a year now-had no problems but must admit the flow rate isn't the same as the hype it's given.

You could run one, then the other or both etc. and give a in field guide.
Like the op/reviewer said clearly the pro is better or is it when everything is considered?
