Hey Bubba,
Sorry you're dealing with this Algae issue. I've done fluconozole 2x with an acro dominant tank. First time like you, I had a horrible outcome with most acros dying when using the recommended full dose. About a year later it came back when I messed with some equipment and changed around a few things. I read from a few others that trialing a much lower dose had positive results. So second time I did 1/3 recommended dose spread out over 3-4 days. This time it was much easier on the system, killed all bryopsis within 3 weeks, and didn't lose one acro. I had a couple bigger colonies that kinda paled out by week three but never bleached like the first go around. I'm not sure of it's ability to kill turf algae but I highly recommend if you go this route again, do it with 1/3 or even 1/4 recommended dose spread out over a few days. If the Acros look stressed within a week or so, it's a lot easier to do a water change and remove the lower dose. Best of luck brother I know you'll get through this!
