The amouont of filtration has absolutely nothing to do with water changes, assuming of course the filter is adequate. So two filters does not mean less water changing. The water change is removing "crud" that no amount of filtration can handle. With the fish you have, i would wonder why two filters; must have a lot of water movement, and you have fish that do not appreciate it.
the 150 i have modded to just create surface agitation. while the AC 50 will move the mid to bottom levels of water. they are both on the same side so one half of the tank is alot more calm than the other.
