In my 75 gallon I have a Fluval Fx5 and an Emperor 400 for filtration. While I know this is probably enough to keep the water clean as my Oscar fish grows, I was wondering if anyone thinks if adding another Emperor 400 to the tank would be overkill? The tank only has my one Oscar, Wolfgang. Thanks!

i never thought i would tell anyone that they had enough filtration as most people under do it but you are the first.)))))congratulations. I personally think you have plenty and will only be using more electric than you need to.

Time to start thinking about more tanks now. No just kidding.)))))

I agree with marcus you have plenty of filtration

yeah, marcus is right... i believe you don't need
an additional filter. the FX5 and Emp400 are more
than enough. another tank or standby unit would
probably more practical
