Browning, darkening

[Aquatic Image]

Everyone I may be running into a slight problem. I have 2 corals that seem to be browning a bit. One is A. loripes and the other is A. millepora. It seems strange b/c I had a stag that was in the dark and is now coloring up since there is now more light over it. Things that have changed is the lighting. I went from Hamilton 14's to Phoenix 14's.
I am dosing PIF & IC twice weekly.

What can you suggest? Thanks

Hi Dustin, browning can be from many causes. Photoadaptive measures by our corals to the new, different lighting? I'd hold all supplements for 10-14 days & observe your corals, then report back. Thnx. Bob

Will do. Thanks

Bob over the past couple weeks I have watched these two corals very closely. The loripes does not seem to be any different but the millepora does. Now developing blue tips on corallites. I am going to continue with my normal dosing. I think it was just the change in lighting.

Hi Dustin, thnx. for the F/U. If all but one "ugly sister" is coloring, I'd stay with your regimen, & try another placement location for the loripes, even if it's lower in your reefscape, it will color, but that may take months to occur. If others are darkening, or their tips are not a bright color with other signs of zeo-excess appear then dosing adjustments will help. Bob

Thanks Bob. Unfortunately where this coral is placed is the only location available. And what is strange is that I have had this piece for well over a year. Anyway, I will give it some more time. I appreciate the help!

Hi Dustin, I'd further consider two options, ZeoSpur2 use, & a trial of increasing all zeo-dosing by 50% for 2 wks, & observing the tip coloration. Bob

An increase is dosing huh. I will give it a shop and see what happens. I know Spur2 will do what I want. I have used it a few times. I give an update in a couple weeks as to what happened with my increased dosage.

Well, this coming Friday will be 2 weeks with my dosage increased by 50%. Once I started the higher dosing within 2 days the A. loripes colored back up to what it was before my change in lighting. thanks Bob.
So all are back to normal except one. It has not changed for better or worse. I am sure it will come around sooner or later.
As far as the increase in dosing, it has not seemed to affect any other specimens in the tank. Things seem to be normal. I am not getting any ZEO excess signs. I am going to continue on with my current dosing regimen for now.:

same thing happened to me when I switched to the ac 14k's. A lot of my corals turned brown.
