hehe, thx, thx. well, actually, the inlets on the bottom are connected to the fx5, but the overflow box and the return hoses on top are connected to a sump, and da's an open sys. the worst thing that can happen is that the water drop below the over flow box tooth lvl, which is not all that much water. i'll probably have to dry my floor a few times though XD
i'll update u guys w/more pix later
