SPS coral question

arafas · Oct 24, 2019

So I have 90 gallon tank that does really good in a mixed reed as you can see from picture attached. I recently connected a frag tank to the same system using radion xr15 g4 pro. On the main its hydra 26hd with t5's. So basically i cut a piece of a green slimer that you can see on the left side of the picture and added to my tank it started losing color and turning brown. I checked par levels and they are the same par in the main tank and frag tank. Can anybody help.

May be the lack of T5s that's causing the color change. Seems like the only variable that's changed. Also, additional systems plumbed into an existing one can still go through small cycles.

However, I'd point to the light change. It might be same par, but not the same spectrums. How long did it take to lose color?

I agree with Flock, could be a cycle in the second tank as well of a different environment and lighting can brown a coral easily

It could just be the stress from cutting, but the lighting is defferent, so it is probably acclimating to the new light. Give it some time, and it should color back up. I have my grow out tank plumbed to my main sump, with the exact same lighting as my DT, and when I cut certain pieces, they brown out in the grow out tank but then eventually color back up. My ASD Rainbow Milli turned totally green for about a month, but has now returned to it's original glory.

The frag tank was up for like 6months, I have a lot of coraline now. I run the same AB + schedule that brs did for hydra and g4 but yes only different is t5.
