I hardly see any arguments against having a refugium. The only people who do seem to be simply unsure of its benefits. I personally thing they help a lot. Particularly as a breeding ground for microfauna. Its fairly well documented that by running them on a reverse cycle they help keep ph up during the night. Plus, if you decide it's not doing much, or enough, you can just throw some new lights over it and turn it into a frag tank.
