Please Help! Cloudy Fish Tank (i have african cichlids)?

when i got my cichlid tank it was cloudy at first too. and thats because when you put the new gravel in the water, the water will clean all of the dust off of them and it will make the water blury. and also i would feed them pellets if i were you, if your not doing that already. but definately go and get some top fin water clarifier. it works miracles.
