Pipe organ not doing well

[svynx]

This is the first time I've dealt with something like this. No clue what it is. It's my fault for letting things go this long. This is a white pipe organ with the normal red tubes. The skeleton, which should be red but is more of a purple color now, has this clear/iridescent film on it which doesn't go away when brushed. I've tried to identify it, but have not come up with anything. Do any of you know what this film is, and what should be done? My other pipe organ is doing great, as is all the other coral in the tank. I'd hate to loose this one as I've never seen healthy white coral.
