According to a study the heavy use of activated carbon in marine aquariums can cause Head & Lateral Line Erosion disease especially on fish in the Surgeonfish Family). This allegedly can be avoided by using a trace element additive in the aquarium. Head and Lateral Line Erosion (HLLE) is a type of skin erosion that affects some species of marine fishes in captivity. Due to that information it is not advisable to use activated carbon in a marine aquarium, and specifically not for surgeon fish.
