Keeping Sand Clean

[tim514]

I have been looking at pictures of people established tanks and the sand is so white and clean looking. My sand tends to be brown with alot of detrius looking stuff. I have enough water flow, but I am not sure if I have the correct CUC setup.
 
How do you keep the sand clean?
 
Also, I have a 48" Coralife 4-65w PC for lighting. Would this be the cause?

I have a golden headed sleeper goby that keeps my sand clean. The drawback is he puts sand everywhere and anywhere. What size tank and what do you have in it?

Had a Lawnmower Blenny but he suddenly disappeared and I haven't found him since. Moved all the rocks and no sign of him.

My sand has been kind of nasty lately so I added some extra snails, hermits, and a cleaner shrimp to my saltwaterfish order the other day. I put them in and in the morning I could honestly tell a difference in my sandbed. They have scavenged the hell out of my tank. The key is to have a mix of species in your CUC.
