I live 5 min from the beach and my back yard is even mostly sand so it seems kinda silly to go pay money for something thats free. Would there be anything wrong with this as long as I screen it good and boil the **** out of it???? There are a ton of different colors of sand and grain size depending on which beach I go to. The stuff I want is about 30 min south but it would look so good in an aquarium. It's almost like micro rocks more than sand if that makes any sense. It has different colors of brown, tan, white, black etc etc. It really just looks like very tiny river rock I guess would be a good way of putting it maybe the same size as #20 pool filter sand. Is there anything wrong with this idea??
