Help! A galexia fell on my prized chalice while I was in vacation. When I got back, I threw away the galexia and examened the damage. There were dead spots where the galexia had been. This just happened last sunday. I thought that if I just left it alone it would heal. However, I have noticed the white spots are spreading! Also, everyday debris seems to be accumulating on it, and I have to vacume it off. Here are the pics:
Brand new chalice (so pretty :'()
Chalice couple days after accident
Chalice now (2 days after last pic)
The chalice is in my 2.5 pico contest tank (http://www.nano-reef.com/forums/index.php?showtopic=69606&st=80).
Its under two 9 watt flourescent lights (one actinic and one 10k) being run for 13 hours a day. I did a waterchange last sunday with catalina water.
What should I be doing? Is the vaccuming off debris daily a good thing or a bad thing? Will I have to cut off the dead parts? (I sure hope not)... Should I be dosing something?
