Put a FREE ad up on Kijiji with the details and a pic telling them to go to 900 block of Bob Street. Put the tank at the end of your driveway, or on your lawn. Put a FREE sign on it. It will dispose of itself.
I've gotten rid of so many things this way...disgusting old vacuum, window blinds, old mirrors, rickety chair, used clothing/towels. It's amazing what people will take when it's free.
