I've been recieving some great advice on this from Brenden; thanks for your help. But I decided to post about it because it's kind of an important issue. Obviously, if my xenia crashes, that's a bad thing so i want to make sure i avoid that.
The entire 3-4 months i've had this stuff, it's look awesome.....and continues to grow fairly quickly. Then about 2 weeks ago, it just didn't look 'as good'. It didn't look like it was going to die but stalks of the xenia looked shriveled. I recently switched salts from Reef Crystals to Oceanic and I thought maybe that was the reason. I also added some more corals about the same time...but i'm less suspicious of that being the cause. So, I dosed some iodine just a few times because i don't have a test kit for it...but i knew that if i only doesed a little bit, there's no harm done. So far, it's been maybe a week now since i did the first iodine treatment and the xenia looks better but not completely. The picture will show you one of the stalks, labeled as "good", that has come around and looks like it's improved....then there's one labeled "bad" which hasn't improved or worsened.
So, my quesiton is, what does this look like to you guys? Am i over reacting and this isn't a big deal? Or is there a reason for the xenia stalks looking shriveled? The poylps still extend as normal it's maily just the stalks that look bad.
