I've read a few posts on here about people setting up larger tanks on a second floor. I just got a 150 gallon tall tank today 48x24x31. My stingray is growing fast and I just want to have everything so I'm not in a rush when she needs a bigger tank. Im concerned that 1254 pounds of water plus the 300 or so with the tank and stand is going to be to heavy to put on the second floor. I live in an apartment and I don't know what size joists or how it was constructed. I could put it on the first floor but I would prefer to have my stingray next to my bed where I can see her the most. I just would like to hear peoples thoughts and if you have done this.
