    Fellow reefers, I was just curious about whether you preferred black or white sand. I'm going for a clean, petite, minimalist look so I'm using a pico aquarium, but can't decide on what sand to use. Which looks better under blue lights (no option for just whites)? Which looks cleaner? Do you...

    i have a 20 gal that has been up for about 10 months that i have recently been vodka dosing. i was cleaning off the rocks and found that under the topcoat of sand my sand was turning black. is this the result of vodka dosing? I had heard that it will cause a black sludge.
