Hair algae in my Chaeto?


New member
I've got hair algae in my chaeto. I have a small refugium. An experiment to see if I can grow chaeto and maintain a healthy population of pods. The light I have is a smalll Pico led. Chaeto Maintains. But I would t say it's growing. But the hair algae is. Any advice? Light runs 7 hours at night with 6 bulbs in the 660 nm red amd one bulb in the 450nm blue. Adjust the light cycle? Too long? Thoughts?
