I had actually thought about that. I originally ordered the tank to plumb into one of my systems and ordered the sump on a whim thinking "why not a stand alone". When the tank and sump had a manufacturing error I just took that as a sign that I should have followed my original plan. It's no problem really. Just disappointed in the quality a bit. I already started the plumbing remodel to fit the frag tank into one of my current systems. I feel that it will suit my needs better anyway. Thanks for the input!
