Tank bows out when full....please help

[reeferaddict]

I have a 33 hospital/quarantine and when I fill it, it bows that much, I've never given it another thought... on another note, my 90 had it's centre brace POP after being set up for 2 1/2 years... I was there when I heard it... You ALL could have heard my heart beating! I immediately dropped 6 inches of water out of the tank, grabbed some clamps and removed the centre brace, cleaned and prepped it, re-siliconed and clamped it back into place without having to empty the tank and no loss of livestock.... *PHEW* The glass actually bowed a little more than 3/8"... quite a bit for a 4 foot chunk of glass!
