Having read many reviews both good and bad on several filters I was wondering what the general opinion is on here?
I'm looking at either of these for my 240L tank.
Fluval FX4 - I like the idea of filter the attachment for cleaning, highest flow rate, however, will have to restrict the flow to get through an external heater as 16/22 seems to be the biggest fitting on an external heater.
Oase biomaster 600 thermo, has a built in heater which meets my goal of not having the heater in the tank, lowest flow of them all.
AquaEl Ultramax 2000 highest flow rate with 16/22 tubing prefiter looks more sensible than the Oase one.
