Nice rock work !! Whats up with the 2 difrent color sands ???
My Self i still wish i went with black sand. well actually right now that my tank is doing great it doesnt really matter, i finally have no more light brown film on my sand, so im happy regardless, But i would love the Black sand cause i would not be able to see the purple and all the crap you see under the sand bed in the front of the glass under the surface.
