ok now for the question.....
Do SPS color brown due to high nutrients?
If you were to get a brown Frag like I did how long in good tank conditions would you expect to see color?
My current tank stats are Ammonia 0 Nitrates 0 Nitrites 0
Phos 0 Salinity 1.025 CA 420
Dkh 9.8
Temp 80-81 F
90 gallon display with 2 250W Reflux MH 12k
4x 48w T5 Antinics
This is the Bali... before it had blue tips. I cant get a good picture with it now.  |
Your tank parameters are perfect. That indicates, to me, that it's not high nutrients causing it to brown. I don't agree with the high nutrient theory in the first place, unless it's extreme. Then other factors would come into play like excess algae growth. It's evident in your picture, that's not the problem.
In my experience, when
Acros lose color, it's caused by a change in lighting. I have found that by moving the
frag higher or, in some cases, lower in the water column colors reappear in a few days. I'd move it toward the lights a couple of inches and watch it carefully for a couple of weeks. I
would not take it to the top because that much change all at once could cause a different problem,
bleaching.
