I had had this acro frag for about a month now I think. It was on my frag rack acclimating to the light for 2 weeks or so and then I moved it to its home. It has been perfectly fine, and starting to encrust the frag plug, I came home 2 nights ago to see it like this, and it was fine the night before. Alk is 8.0 Calc 460 mag. 1420 Nitrates 2.5. I have not changed anything to the tank, and all my other frags are encrusting and showing no problems.
The frag was about half way up on the rockwork medium-heavy flow, and 2X 250 watt lighting. I moved it to the sand bed last night and today all the spots that have the brown algae looking stuff have polyp extension(except the very top brown pieces) and it is looking less brown on the tips.
I am curious what caused this since it is only one one side of the frag. Is it not getting enough flow from the right side?
thanks in advance
