Are you positive it's bryopsis? Are you skimming during treatment?
Yes. Bought frags from a local fragger who was battling it. I never had it. I couldn't see it in his tank, so I shrugged it off. Mistake. For months and months it was just a small patch on a rock. It just looked like moss and kinda cute so I left it as is. After about two months of dosing nitrogen it suddenly took off. It was everywhere. I dosed fluco, above recommended strength. I started seeing impact only into 2nd week. I did stop skimming as it causes skimmer to be over-excited. stopped carbon too.

Now when it comes back, its usually on the same rocks and same places it used to grow on. And right on top of coraline algae.

Has anyone ever had fluconazole kill a fish? My Moorish idol that I've had for approx. 9 months suddenly appeared dead today. He has otherwise appeared healthy. He was definitely eating yesterday afternoon, his color looked great, he was active and swimming normally and briskly. Everything that goes into the tank goes through quarantine (TTM +prazi +metro or a 60+ day invert quarantine). I haven't changed anything other than dosing fluconazole (4000mg total guesstimated 20mg/gal Reef Flux though might be slightly higher than 20 depending on actual water volume which is a Red Sea 750 that has a total volume of 200g and a co-plumbed 25g lagoon) Friday afternoon and a 50g water change with my normal Red Sea blue bucket before the fluconazole. Yet here we are mid Sat and the idol was sucked up against the powerhead dead. Other fish look fine, corals look fine. It just came as a huge shock as he has looked super healthy and eats great then bam.... Any other thoughts then? I wondered if maybe this was unusual enough of a fish that people hadn't tested one.

Other parameters:
SG: 1.026 (calibrated refractometer)
pH: 8.26 (Apex probe)
Alk: 8.0 (Hannah)
Phos: 0.03 (Hannah)
Ammonia: 0 (API, yes, I know. I won't buy more when it's empty)
Nitrate: 0 or super close to it (API)
Ca: 350 (Red Sea, lower than I'd anticipated)
Mg: 1120 (Red Sea)

Well, I will start by saying sorry for your lost. But I highly doubt fluc had anything to do with the fish death. First error you are making is testing with API specially after 9 months. That’s only a test while you cycle test kit and should be put away after the cycle is complete. I will recommend testing with salifert and because you are not able to do any water change while treating with fluc and you saying the fish was eating fine. I will think amonia spiked and might be the issue. Test with a better test kit first to see the real issue here.

With all that said, no fluc does not affect fish.

Before the 1st treatment it was in alot of areas but I would just RIP it out. Then I started contemplating the fluconazole treatment and one day decided to do it and within 9 days I could not find any it worked quick, that time i followed the exact directions the OP posted. Then a month after it started showing up again, so I changed to half the dose and only turned off the skimmer for a day and it was gone just as quick as the 1st time. Though this time I left it in for 28 days. The third treatment I did the same as the 2nd one but left it in for 38 days. It took roughly a month before it grew enough in a couple spots before I noticed it yesterday. Gonna start treatment #4 in a couple weeks probably the same way as the last 2 and leave it in for maybe 2 months this time cuz it does seem to not come back in all the same places when it is back. I have alot of corals and fish and haven't seen any negative effects on them the last 2 treatments. Hope that answered your question.
Thank you I'll keep at it

I'm now 4 months post fluconazole treatment and still no bryopsis :) I kept my skimmer off for the first few days and the mexican turbos and algae blenny started going to town on it after about 2 weeks when it started to die off.

I dosed fluconazole 3 days ago in my tank. I know its only been 3 days, but I havent seen much of an impact yet. My tank is 45 gallons, but i put 4 pills worth of Reef Flux not wanting to over do it trying to measure half a pill. Should I go ahead and put another full pill in or continue waiting it out longer?

Also, 3 days in - although I havent seen much happening yet - should I go ahead and turn my skimmer on or wait till I start to see some changes?

It may be too soon to see anything yet

If it were me I would go with a lower dose than recommended and keep it in there for longer. I've had to do it a few times went with the full dose the 1st time and my sps acros didnt like it, so the next few times I went with half the recommended dose and it was just as effective. Since I dont see any corals react negatively at the lower dose i keep it in for a month. It's been 4 m ok months since i removed the meds from the last treatment and i just noticed the bryopsys starting up again in a couple spots pop up. Will probably start another treatment soon.

Hey I’m currently a week into a Fluconazole treatment and can see the Bryopsis dying, can I scrape the dying algae off my glass? I’m assuming with the treatment in the water it wouldn’t be able to reattach and regrow anywhere?? Just get sucked into to filter which I currently only have ceramic and phosgaurd in...

Hi, has anyone used Red Sea NOPOX while treating with Fluconazole to keep the Nitrates down? Just wondering if there's any negative side effects.

Thanks
