I just picked up a bowfront 46 gallon for really cheap from my job. It was returned by a customer but appears to be fine just the brace is wobbly and a bit bowed inward but is still all connected. When I push the back and front glass outward the brace straightens out. Is this normal and/or safe? I am guessing the brace got a little loose like stretched out since it was filled before. I assume once I fill it, the pressure of all the water should push the glass outwards and make the brace tight and straight again. Hopefully someone else is more experienced with this. Let me know if this is safe and/or normal.
