Oh guys. I've got good news!
So today I revisited my Petco and there were
only 5 10 gallon tanks, and 2 29 longs left. The manager
said he would call the other stores and there was 1 left
in another store. I went there and picked it up! When I finally
got home, I wasted 2 hours trying to make my 3 wooden poles
flat so that the tank was crooked. My dad and I lifted the tank
a total of 4 times with the water 1/3 filled just to make the tank
stable. It's all worth it, just a little price to pay, bleeding fingers
and glass splinters. I really don't know how the I got the splinters.
