Go garage saleing, I picked up a 100 gallon with no cracks and some slight reflective tarnish in the glass that won't ever come off for $10. $100 for a cracked 75 is insane, you could buy a brand new 75 in the box here at a fish store for about that.
lol i don't think anyone realizes that this comes with a 200 dollar stand, hood and lights, 100 pounds of gravel, and 60 dollar filter as well. It's not a bad deal, i just want to know if the tank could be fixed.
