guys the purple rock is not live rock its called Carib sea look alive its designed to do the same job as live rock so break down ammonia etc and it also builds up the cyno algae faster its incredibly porus so no there wont be any kind of cycle as its not real live rock didn't come from any ocean :P as for the cloudy water that was from me moving everything around and placing the rock as for the pink look lights make it look very pink till I replace them anyway
