Are there different types or RTN?

Hello everybody,

I've been thinking about this lately. I have observed three different kids in my tank:

1. This is what I think most people call RTN. You look at the coral and some it it is just bone white, nothing left. Come back later and even more is bone white.

2. I have seen the flesh come off, in matts, with full color and polyp extension. It is like peeling a sticker off glass or something.

3. The color seems to sink into the skeleton. The whole coral becomes blotchy with skeleton showing through, eventually losing all tissue.

Anyone have any thoughts?
 
I think theres only one type of RTN. But there's different causes of RTN. Temp, alk. RTN is caused by stress or so it is believed. JMO
