Algae needs light to grow, the faster it grows the fast it dies with fluconazole. Turn your white(and red if have it)--- UP---. You should start to see results by the end of the of the first week. Pictures of about half of how bad my GHA became,and same spot now. Oh vibrant also killed my coralline algae.
What an interesting take. I never would have thought of it that way. Thanks!
