i live alone, and work on my tanks alot, there has been many times where i would pick up my tanks by myself ( whether a 2 foot 20 gallon up to a 4 foot 75 gallon ) since i have been on my own, i have on numerous occasion picked up my 55 ( with sand ) by myself. heavy, yes. but i get it done. anyone else pick up there tanks over 4 foot by themselfs?
