How to move a 700 lb fish tank with one guy?

What does it cost to maintain a 150?
I honestly can not say as I dont have one yet. Im using Red Sea tanks, right now I only have my 34 gallon up at the moment and as soon as this tank is established I will be moving it into a 65 gallon. Eventually moving up in tank size to a 150.

Im not sure if your into the hobby, but the initial startup is not cheap. This hobby is just as expensive as owning cars. You can get basic equipment from the start or you can buy top of the line. Just my 34 gallon I have well over 1k in equipment. I found the tank on Craigslist for dirt cheap so that is a plus and that doesnt include the live rock, live sand, corals or fish.
