Hi, Mine took about 8 days and its trackable the whole time.Deffo interesting - I had Bryopsis either come in on a frag (couldnt see any evidence), or possibly rooted in the Aquaroche I got 2nd hand with the tank, and have been battling it ever since, got despondent with the tank, and stopped water changes for 2 months, and it seemed to start receding, as things were looking up, I thought I would run a water change (made up with AF probiotic salt), and boom, Bryopsis came back with a vengeance. Have tested new batch of water and levels are all spot on, wonder if something in the formula of AF Probiotic salt is feeding the Bryopsis.
Anways, I have been advised that my order of Fluconazole has been despatched, so waiting for it to get to UK, and I have everything I can crossed that it will kill off this b*stard "weed", and I can fall back in love with my tank
) pics haha. I won't be turning the skimmer, carbon, PO4 remover or ATS back on or doing a WC until at least day 21. I'm even thinking of trying to get another dose of Fluconazole from the Vet to re-dose on day 14 and just do a second treatment straight up. 
Here's my final video
Thank you! They are DIY Rock and are live
So not to discuss this on this thread, here are links to where I show how I did them. 
My order was made on the 16th, dispatched on the same day and arrived to me in the UK this morning, pretty good service. It's sent special delivery so you have to be in to receive it but don't need to sign for it. They won't leave it with a neighbour.Deffo interesting - I had Bryopsis either come in on a frag (couldnt see any evidence), or possibly rooted in the Aquaroche I got 2nd hand with the tank, and have been battling it ever since, got despondent with the tank, and stopped water changes for 2 months, and it seemed to start receding, as things were looking up, I thought I would run a water change (made up with AF probiotic salt), and boom, Bryopsis came back with a vengeance.

No it won't, sorry.
You could try h202 treatments or Vibrant. I'm on my cell ATM but do a search on R2R for treatment options and possibly someone could post a link or 2 for you via pm. @twilliard
Update on my Fluconazole treatment for Derbesia. Day 12 so far.
Very minimal to no change between days 0-8.
On day 8 I noticed the tips of 60-80% of the algae had started to turn white and most of the algae was looking kind of wilted.
Again very minimal change between days 8-12. I would say 95-100% of the algae now appears to have white tips and looks a bit wilted, however absolutely none of the algae is gone or even has more than just white tips, CUC (lots of trochus and turbo snails) and tangs are still not eating it.
Fish, clams, coral banded shrimp, coral and snails are all fine. However I have not seen my abalone or long spined urchin since day 1 of the treatment. Both are fairly small in a 6ft tank so they could be hiding, but I would still usually see the urchin at least once a week, if not more and the abalone had only been in there a week. I thought both were just hiding but now I'm not so sure.

I quit vibrant before using fluconazole. Vibrant caused a severe cyanobacteria outbreak. I quit it's use and treated my tank with chemiclean. Then was told about this thread. I beat it in my 180 without vibrant
