sorry I ment in our average tanks.. I personaly like to keep room open around the reef to clean the glass easy.. don't know about you or anyone else but if I had the room I would have a large sand bed for the LPS that don;t need 400 watts of baking MH but in reality I would probably end up with to much rock and fill that up also...
either way a MH can light a 30" didstance with little trouble.
