What's the LONGEST (in terms of days) have you've done a blackout of lights?

Did you suffer any coral loss/death?

(For a GHA outbreak... I'm on day 5... but I have 95% zoas/palys)

3 full days, no coral loss & had just lps at the time. Went until my gha was white and loose enough to be pulled up with weekly water change. I added microbacter clean as well (I had gha and cyano). Clean up crew removed the rest.

I went a week. Things were ticked,Acro's browned,Acan's recessed but within a week or 2 everything was as good as gold.

I just used flucanozol for GHA and it killed it all
