well i have this 55 gallon tank that has a crack in the glass of the bottom of the tank. i called my lfs and asked what i could do, i had planned on using sealant to seal the cracks but they told me that i would have to have the glass replaced. so then i called a glass repair place or whatever and asked about having some glass cut to place in the bottom of the tank and seal it that way. does anyone know what i can do? my neighbor was throwing the tank out and i said i could do something with this tank and not let a good thing go to waste. all advice appreciated. always in advance thanks!!!
