New issues
About a week ago a patch on one of my completely coraline encrusted rocks bleached out. A few days ago a whole colony of zoos began to change from their usual green and bluish color, to a yellow color. I guess they are bleaching as well. All other corals are fine so far, I'm hoping this will stay localized. Any suggestions or comments as to why this would happen just in these two spots?
Additional: my Ca was a bit low (300ppm) for a day or two last week. Did water change and prostrata acro spit slime all over tank.
