I have a pico tank that's about 9 months old now. Mostly LPS, a few zoas, and some SPS.
A rainbow monti frag was one of my very first coral. Over a couple of months time, the green and yellow polyps turned orange. I thought maybe that it was a Fruity Pebbles sold as a rainbow. Soooo, I bought another one. Again, in a month, the green polyps turned yellow. Then in another month, it turned from yellow to orange.
The coral itself is healthy, growing, and encrusting. Just wondering why I can't keep the polyps green. I upgraded from a Kessil A80 to a 360X. I have an 8 hour photo period that peaks twice at 70% intensity. Color (white) peaks at 10%. The 360X is 8 inches from the water line, and the montis are three inches below the surface.
My nitrate is less than 5 constantly, and my phosphates are always between 0.05 and .15. Flow is moderate. I dose phyto twice a week, and Red Sea AB+ once a week. Salinity is 0.34 - 0.35 ppm, Alk is 8.5 - 9.5, calcium is 440~ish, mag is 1260~ish.
What am I doing wrong and how can I get the coral to color up (green) again?
