Definitely. I used mine 24 hours later
Well it's about 3/4 full but I just realized something while filling it up... the back panel has a clear strip at the bottom too since the trim goes a few inches up lol. Should've noticed that before but I guess that's how all glass tanks painted from the outside would be. It creates a white strip along the back edge thats stands out pretty bad though. So definitely paint from the inside if you're going bare with a painted bottom lol. I just shut off the pytho so I'll post some pics in a sec
