I decided to put some sand in a new 10g tank this week and love the way it looks. i used pool filter sand because its cheap and white enough for me. i have heard some good and bad about it but want to hear some people with long term sand in there tanks. seems like not alot like it due to seeing the fish/shrimp droppings lol, on the sand. and algae growing on it. anyone have sand nightmares?
