Can't say enough how much of an inspiration you and this tank are. I especially love the fact that you simply rely on good old fashioned husbandry, heavy feeding and good nutrient export.
On that note I have recently begin feeding my fish and coral much more than before. I have been 0ppm No3 (salifert) & 0.00ppm Po3 (hanna) for some time, I have noticed a improvement already. Anyway some cyano has popped up in small patches much like the picture below. Normally I would freak out at any sign of algae and feed sparingly....I was wondering what do you do when small patches of algae or cyano show up? Wait it out, act or just forget about it.
Beautiful coral by the way.
