i am guessing i had better find a vivarium forum to ask these types of questions but here is the first thing i need to know.Would i have to remove my built in overflow box?What to do with those holes that are presently there?I have seen some vivariums with waterfalls.Is my sump and return system capable of handling that kind of duty?Man,alot of dang questions pop up.
Thanks guys and gals,
Mike
