Tank stand solid steel welded sturdy, 55G sits on it now with about 2 1/2 inches all the way round I think it'll be good up to a 75G tank, has light underneath for viewing supplies or you can put another tank down there, dont know what it's worth, I am willing to trade for anything marine related for for fish, if you want to buy it let me know a price, I will post a picture of it as soon as I have a decent one. Thanks
