It looks like my algae scrubber is going to bottom out my nutrients. Is there a minimum time that the lights need to be on to at least keep what algae that's growing on the screen alive? I'm amazed how effective this device is. I barley have any algae on the scrubber and my phosphate went from .07 to 0 and nitrates from 10 to nearly 0.
