Brown Algea In Refugium

Since I put the light in my refugium about 2 weeks ago, there is know a huge growth of brown algea along the sides of the refug. I am growing caulerpas in it,,, I assume that it is fine, should I scrape it off or just leave it??? Thanks, Justin

If you leave it coralline algae will probably colonize that area. If you don't care just leave it :)
