Can I give you some advise. From someone who's sold quite a few tanks and reef equipment since I change my mind all the time.
I'm sure most people know what a 50g cube looks like, but it may help if you take better pics of the tank upright on it's stand. Currently, it looks like it's laying on it's back panel on the stand with the bottom panel facing front buried under a few things. It also may help to take pics of the sump, return pump, and skimmer. Give details about the brands and how long it has been used for. Those are things I look for when buying a used tank or equipment.
Hope you don't take offense. Just trying to help you sell the tank. BTW, I used to own a SCA 50g for 1.5 years and I think it's a great setup. GLWS.
