Charles Delbeek and Julian Sprung are very knowing aquarists and have a lot of good information to share. If not for them, many of us would not have started keeping reef aquariums in the late 80,s or early 90.s. I would not discount them on one persons say so, although I have nothing but great respect for Doc. Ron, even though I dont agree with many of his beliefs.
