It shouldn't take too long to remove the sand, if you ever decide to put something on the bottom, why not use aragonite??
I prefer aragonite to sand because it doesn't pack down and trap gasses and because I don't like the bb look. Just use enough aragonite to cover the bottom with a thin layer, another option if you like the black look, I believe Jl sells the black equilevelent of aragonite. My friend used it in his 90 that has been up for 2 years and still looking awesome, got some coraline on the substrate now. Reminds me of a volcanic reef.
