I at my wits end

[Damsel13]

I had a very healthy colony of Zoa's for the longest time along with another more finikey mini colony. They were really growing and spreading until about 4 months ago. Now they are just dwindleing away. I can't see anything on them and I have been blowing this colony that is left with a turkey baster but the heads just keep sheading off and the ones that are attached just seem to keep shrinking.

Does anybody have any ideas what could be wrong? My xenia is doing fantastic as are some mushrooms.

Nitrates are high - 80ppm. Did I answer my own question?
Here is a picture in happier times. (picture to follow)
