So now that I have my my 90g up and running, I'm having an internal debate if I should run activated carbon on my system. When I had the exact same tank set up in NC i had carbon and my sailfin tang had hole in the head syndrome but was healthy otherwise. I have inherited my father in laws fish, including a yellow tang, and want to avoid this same misfortune. What are your thoughts on running carbon in the tank?
Thanks
Jim
