Dirty Sand

[bg7003]

hey,
i have chopped coral and fine sand in my tank. its starting to turn this ugly tanish color and my tank is right around that 6 month time. i dont like how my sand looks. the chopped coral is up on top now too. its this ugly mix. should i take the everything out and replace the sand or what?

I quite like the reef rubble sand mix makes things more natural looking, If its going a brownish colour you may have some algal issues or maybe diatoms and cyno. I would be inclined to leave it and up the CUC a little.
