Fluval U4 Filter?

[dalelewis1]

Hi,

Anyone know if a Fluval U4 Internal Filter will be okay for my 200 litre aquarium with 5-6 discus?

Thanks

As the sole filter?
Is this a BB or planted 50gal tank?
13x3.5x3.5 inches taking up space inside your tank. If this is a display tank seems a little bulky.

Yeah as the sole filter?

Its a gravel aquarium with no live plants.

Seems like a space occupying filter that might not handle the bioload.
If you are planning on sign. water changes then it might do.
I will yield to the people here that have more experience.
