So I have a bit of a question for all. I love sand but can never seem to keep it clean due to fish excrement. When i use sand and I want my tank to look good i have to clean it every day to get the poo away. Because of this I always seem to switch to gravel. So my question is: is there any way to keep sand clean to where you don't have to clean it every day, but it doesn't look like you can see every bit of poop in the tank. By the way I'm talking about black sand.
