SPS Turning Green

[dough]

So several of my SPS have turned green such as my Bill Murray. I've sent off two ICP tests (ATI and ReefLab) this past week, so they're are still in transit. So I don't have parameters available yet. PAR levels range from 250-300.

Question is, when I get the results back, what would be the key indicators that I need to consider that could be the culprits for this?

Iron could be the culprit. Don't know how long you've had them though...could be lighting. If you had them a while it could be the water isn't as clear as it once was....several factors or a multitude of several

What color were they when you got them? It’s very common for most sps to go from brown to green and then it’s true colors as it acclimated to the new system.

I have identical acros in the middle portion of my tank exact same height. One under the left light and one under the right light. Left one is green base with purple and blue branches. Right one is almost all green with just a hint of purple and blue on branch ends. Same vendor for the corals but they are maturing very different in colors even though exact same conditions exist. SPS you get from your vendors just may not end up looking the same in your tank. My last ICP showed no Zinc and I dose 2ml weekly now and acro colors have exploded now especially the yellows.

Okay, let me restart here. The system has been up and running in its current config for over 2 years.

The SPS that greened out were bought having their colors as you would expect.

I just received my Reeflab results!

Perhaps you identified your problem although I feel lights are still a key part.
