Hair Algae!

[Reefer Rob]

Find something that will eat it. I.m not sure what's eating it in my tank, but something is. Try Mexican Turbo Snails, and an Abalone.

Run a refugium with macro-algae. Use a 5500K bulb or so to encourage the hair algae to grow in the fuge and not in your tank.

Run 1200K bulbs or higher on your display.

Use GFO! Hair algae needs phosphates to grow.
