No way you're getting a 125g for $125, whether it's just the tank or not. Nor should you. The $1/gallon idea should only apply to 55g tanks and smaller.
This $1/gallon thing is getting carried away, kinda like the 1 inch of fish/gallon idea years back.
Todays Craigs list in Phoenix a 150 gallon tank for.......wait for it...........wait for it............
$150

Cant say I blame them for almost trying to give that setup away. Looks like it's about to collapse. I guess I should have stated in my previous post that the tank probably wont look like it's ready to crumble to pieces, just assumed that was implied.
Well I must admit I found my tank on craigslist and i got a hell of a deal...70''w by 18h by 12 depth..He never new exactly how many gallons exactly but I figured between 175-200gl's. And so I got the canister the water pump, the tank with hood and lights plus the stand for $200..Now i must say it was in great shape but it definetly need some TLC before I was able to display it. Plus the plumbing need a change..
