Thanks every one for posting!
I am not sure that I will be able to get my 240 reef now 
A couple (may be 1) gal. of Salt h2o split out of my sump when the power went out and into the basement light fixture. So I don’t know if my rental company we let me get a bigger tank or ever kept the one I got.
Also I don’t know if the wood floor in my house will support a bigger tank? Any builders out there with any advice?
Thanks
