Hi reefers,
I noticed the white expanding from the bottom of the acropora, is this bleaching

Yes, either bleaching or RTN/STN. If there is still flesh on the skeleton and no algae is growing over, it is bleaching. If the flesh is gone and algae starts to grow, it is dead caused by RTN or STN.

Sorry I don't have any experience with STN so I don't have any answers on how to stop it, but hopefully someone else will.

Any SPS that I've lost has been to RTN and completely died overnight.

I personally have not had much luck fragging once STN has started but it is definitely an option. I normally just try to make sure water chemistry stays consistent and hope for the best.
