Here is the problem. I was out of town this summer for a week away on business. During that time, my tank was being taken care of but my pectina fell over unto some giant hairy mushrooms; and went unnoticed. All the tips where burned off. The flesh did not grow back as I hoped they might. Instead they started to grow colonies of algae. I decided to try to do some repair.
If you look at my avatar, you will see how it looked, pre-accident.
Now, here it is. Already, I have tried snapping off a few dead tips to see if I can get some regrowth going. You can see where the white areas are is where I made the manual break-offs. I plan to do more but will see what happens with these tips first.
