Cool! Thanks. And to do 2 sides I just throw on a mirror or 2 for reflectors and add another light? And does a scrubber replace a refugium? I would need to take all the rock out of my sump to use a scrubber. Does the scrubber replace all other gear besides my Skimmer? Can I change my sump to just having a drain, Skimmer, and scrubber and not use the refugium?.
