I just got a smoking deal on a used 125G. Only problem is that the tank is filthy and the plastic frame moulding is cracked in a few places. It still feels like it would be very solid when the tank weight is resting on it. I have the tank standing up on its edge right and I can move the moulding if I pull on it. Is this going to be a big problem you think? Could I just glue it back together?
