I dont have any in use ,but have seen a couple, they look pretty stout , yesj ust looked them up again ...pretty much ac 70's with wet / dry effect,,2 of those +2 BIG sponge filters on small powerheads....it'll work fine ...and that way you can keep nitrates down by cleaning a filter with every water change.. be warned though the c-4's may not fit over the trim of a125.. you may have to do something like penguin hob's or aqueon (or modify the tank)
