I bought a used complete 120 gallon tank, stand, canopy and tons of equipment this weekend to setup another system. By the time I got home from only an hour drive, We were unloading the tank and noticed a crack down the back. It wasn't cracked when we loaded it. Not sure if it cracked from heat to cold to heat or what, but I need a 48X24X24 tank. I would buy a new one, but wife said I just spent too much money on all new rock, tank, controllers, lighting, skimmer,etc..etc..and would have to wait another few weeks.
