Ok, I'm picking up a large tank tonight, it looks like a 225 or 240. Only thing is, I didn't see an overflow on it. There's only a small spot in the middle of the back of the tank for anything to go into it (it's an acrylic tank). What filtration would I be able to run on this? I was thinking maybe an fx5 and an eheim, one for mech and one for bio. What do you think?
