to run a small refugium along with a properly sized Algae Scrubber? I currently run a CW200 Algae scrubber very effectively, but I'm toying with the thought that I'd still like a small refugium primarily as a habitat for pods, etc, but also as a fall back. I realize that the algae in turf scrubbers will out compete macro algae, and may may it impossible to successfully grow chaeto. So as an intellectual exercise -- any way to successfully do this?
