Been slowly filling the tank in 50 gallon increments over the last 2 days. Until tada....
I also tossed in the 60 pounds of whitish sand I had left so it didn't look like a black hole when I take pics.
Had one hell of a scare though. I filled the tank enough to test my overflow pipe that runs down to the sump. My sump isn't done yet so I put a cheap wal-mart tub to catch the water. It worked fine. I started draining the tank down below the overflow levels and while it was draining I took the dog out for about 5 mins. I went into the shop under my apartment to check on something and found water dripping from the ceiling. *cue the panic*
Turns out my cheap ass tub had a crack in it and leaked about 2 gallons into my carpet which seeped though the pad and dripped downstairs. The bright side is. The tank isn't leaking and since the floor under my apartment is NOT insulated or sheet rocked. I was able to find the leak quickly and there will be no major water damage from it.
