75Gal tank - put 1 XP3 or two?

2 XP3's on the 75, sounds about right to me.

i have a overstocked 90 and it does a awsome job, the two powerheads might be doing something too...

i agree with the majority on here. keep it cuz you can never have too much filtration. plus even if you dont use it youll already have another filter lying around for when you get another tank haha.

You shouldn't need two XP3 on a 75. I have a pretty heavily stocked 75 with one XP3 and it is fine. I had two on there a while, but it was blowing my fish around. So back to one XP3 and all the fish are happy. Just keep up with your water changes and all will be fine.

If you do run two, I'd slow one down and make it almost completely biological.
