My sump started to grow the algae that is plaguing my display. I cut my lights back from 70% to 20%. My nitrates and nitrates are low which I know means the algae is consuming it. I have chaeto and another macro algae in my sump but they're not out competing the bad algae. I have vibrant on the way but has this happened to you where your refugium has taken on anything but the macro?
