Hi! I've been debating this, whether to use black sand or white sand, for a long time now, and decided I would just ask you all. I really like black sand because it seems like it would make my awesome shells and fish stand out more. Then I thought, is it going to be more difficult to clean? It seems like it would be easy to see and remove waste from the surface of white sand, but black sand, it seems like it would blend in better, making it harder to remove. What do you think? Thanks!
