I recently started seeing some cyano come back after a long absence. I got a frag of mystic sunset acropora(I think), and phrased light to the area to encourage growth. While the strategy worked on the coal, the cyano also showed up in limited areas. I'm fairly sure that if I back of the light, the cyano will eventually go away. Just not sure how well the coral will grow? Any advice? SG: 1.025 Ph:8.0 Nitrate: 5 Phos: .02 Alk: 10 Ca: 450-460 Mg: 1360 I have 3 kessil 150's over a 40B. This light is about 5 inches from the surface and the coral is about 7 inches below the surface. Thanks in advance.
