I have an 8' Pearls of Paradise tank that was used for about 12 hours at the Deep South Koi Show March 29, 2014. I was going to use it as a QT but when I put it up to sterilize it, I found that I didn't have any level ground to put it on. The tank is 30" deep and holds 1,050 gallons. I paid $619, I'm asking $525.
