The tank was heavier than yours, Doc, no joke. An old Oceanic 150 with 10" thick glass. Ok, maybe not 10", but still... nothing to shake a stick at. And there were stairs to contend with. But, we got 'er done. And the rewards were bountiful. Beyond anything I could've hoped for. I kid you not, I was worried that we might get arrested for grand larceny on the way home. One very, very happy woman right now.
