Zoa Pox - How Fast can it Spread?

I noticed a Frag of Purple Hornets where One Polyp had Zoa Pox on it.



Then in a couple Days I noticed another Zoanthid Frag with it.



Then another couple today were infected.



How fast does this Stuff Spread?



I have around 75 Frags in this Tank and have been investing a ton of money into Zoanthids.



I cannot afford to have this wipe out all my Zoanthids.



They were doing so fine for 6 to 8 months and now this.



I have been Reefing for 5 Years Hardcore now.



I know of nobody that eats, sleeps, and drinks Coral like I do.



I just run into problem after problem.



I cannot believe that I am saying this but I am thinking about giving up.



This has been a total obsession and addiction for the last 5 years.



Literally all my money is going into Coral and it keeps dying.



First Acans, then all my Chalices, and now this.



I really do not understand why this is happening.



I know what I am doing and now my Noob Corals are dying.
