Sorry to hear the news Deb, tho it seems we all have to battle them at one time or another. I don't know how well stocked your tank is now with sps but I would suggest treatment sooner than later.
I had a bout with them last year and it was a simple thing to treat-hydroids were way more of a pain in the a$$. If you leave them too long, before you know it they will be everywhere and your acro's polyps will not be able to open. I ran a hospital tank with all my sps and a smaller dose of interceptor for about 3 days and I haven't seen any since-tho I'm sure they will be back one day
