I just did a conversion. It seems that it's a 225 gallon and using this --> http://boonedocks.net/fishtank/ftweb.php the weight of the empty tank is estimated to be about 550lbs.
no way it weighs that much me and my bro hauled my 125 up some steep stairs and he cant weigh more than 145 soaking wet if he can haul a tank you can get it down one flight of stairs if not send it to me and ill take it up the stairs into my place
I dont know. I used an online conversion thingy. It states that the tank is 544.16lbs. Taking that its 5' x 3' x 2'. I just went to check on it. Apparently its width is not 2' but about 1.5' but it's height is about 3.5' and not 3'. So it's probably around the same weight anyway.
if u cant take it down from the fifth to the fourth floor, just ship me ur tank i'l take good care of it. while u try and figure it out.
talk to ur building attendant. there gotta be away too bring in over sized funiture.
