Where did my coroline go?

[jsr]

Okay guys/gals. I have been trying to figure out what is going on here. I have a post on RC with a few suggestions but wanted to see if anyone has other opinions.

I hope this does not violate the rules of the board by posting a link. If anyone has other suggestions, please let me know. From when this was posted, there has been no growth on the rocks/glass.

I haven't checked your RC thread, but what is your Magnesium level?

Nevermind. I clicked through. Im stumped.

Yeah, I dont know what to think. I find it hard to believe that changing two bulbs would have killed the coraline. There was 70 pounds of good rock, mixed with 100+ pounds of Gabes old rock in the tank when it went south. The only thing that I can think is the KH drop had something to do with it. I just dont know what to do at this point. I dont have/plan for a reef, but I want the coraline.

I would have to agree that the new lights are the culprit. I have noticed a similar fading when changing bulbs and then it comes back after a few weeks.
