Hi there. I am setting up a 20g reef only tank. I am not sure what the lighting is going to be yet until Santa comes this week. 
My question is, if this tank is reef only, then do I necessarily need it to be cycled? The tank is already cycled, but I wonder what will happen with no fish in there. I have 2 algae eating crabs, and several snails that are breeding quickly. Also, Will I need as much filtration with a reef only?
