So I am a SPS newbie and looking to make the plunge soon. The dipping you are referring to is for parasites etc before placing it to your main tank? Is this loss of color common?
depends on the dip, strength and duration. Some SPS are more effected than others. The aqua cultured frags usually hold the best color through anything.
I dip really strong and stress the corals abit, inspect for and eggs etc, re-dip then qt and repeat.
