Good day fellow Fish Geeks

Well a little about myself. I have had a freshwater aquarium for
several years. Probablly for a 20 years off and on. I am purly a
hobbist and just love to have fish in my living space. The tank social
structure is just awesome. Once I bought my first canaster filter there
was no turning back, I have mainly used Fluval. Just due to price and
they have always done me real well. I still have a 03 series and it is
still in better shape then the o4 I own. Here were in lies my question
my 120gal needs a new filter and I am torn. My fluval 404 was a
dispointment the quality just was not there.

Choices?

1. Ehiem
Big Price every store owner always tries to sell these. But I
know absolutly noone with one.
so my question is are they worth their high ticket price. any
major opinions about these canasters?

2. Fluval FX5
New filter design being the Mechanic I am (pumping fluids is in
my trade) I real like the new design with the pump out of the lid and
at the bottom. To me this means way less cavitation the killer for
centrifical pump. Has anyone purchased this filtration system, or have
an educated opinion on it.

3. an other recomendations on filtration?
