Hello, I wanted to share the algae scrubber I built for a rear sump with a lamp for refuge, I want to remove nutrients in a natural way by the algae, what dangers are there in this and what should I know and be careful?, there is chato algae and hair algae.Should I turn on the refuge light while the light in the display tank is off or turn on both at the same time? I turn on for 10 hours, is that enough or more?
Thank you for your response
