i have some of that tropical white sand (not sure the name) in the front of my tank and i just cant keep it clean. it seems like within an hr after cleaning it will already have more shrimp crap on it. just ive also had what seems to be a kind of algea outbreak on it. most of the top layer of sand has turned a slight yellow, but i can stir it up to reveal clean white sand.

my question is whats the best way to keep this stuff looking good in clean like ive seen in all the pictures???

thanks
