I just read through this and loved seeing the evolution of this tank! Beautiful!! I wanted to go back to the "beginning" where you started with light colored sand. You posted that you changed it out because you didn't like that it looked dirty, can you elaborate on that? I went and bought 150lbs of black diamond blasting sand today, and after hauling it all home, hubby said he felt that it looked unnatural and asked if we shouldn't do a lighter colored sand instead...
But I have to give it to you, this thread was awesome to read and see the evolution of the tank, all the way from light to dark sand!
