I am going to maybe start filling up my new 50 gallon aquarium after my family and I get back from visiting my grandparents. I definately want to do sand, not gravel. How exactly do I wash the sand? and I don't know if I want to do black or white sand...any suggestions? my tank is going to have livebearers with very bright colors 
And how much sand would I need for a 50 gallon? I want it to be pretty thick...how do I figure out how much to buy?
