I will soon get the 75 or 90 gallons freshwater aquarium from Petco (build your own aquarium) which can come with an optional overflow unit.
Unfortunately, it does NOT come with the sump filtration unit, return pump and replacement filter pads.
I have to be honest and admit that I'd want a system that is not too high maintenance and therefore I am considering the Fluval FX5. I am really excited about it.
I am looking at getting a Tropical fish "community" aquarium with several types of fish ( around 50).
My question is:
Will the Fluval FX5 provide enough filtration/flow to be used without the Overflow system? If not, can i install a second Fluval or alternately a filter under the gravel?
EDIT: I got my answer here: To Sump or not to Sump?. Please delete the thread if you can.
