This algae exploded in my 4 month old tank 2 months ago after adding a bunch of frags. I thought it was just a hair algae bloom, but it grows differently and is much more brown than any hair algae I've ever experienced. My nutrients have also always been in check, PO4 never over .06 and NO3 never over 10. Ever since this algae started growing everywhere, my corals have lost a ton of color and aren't growing very well, as well as coralline growth coming to a halt, almost like the algae is stealing all the nutrition they need. PO4 has also bottomed out because of this, and I've been dosing it to keep it around .03, and then today my nitrates bottomed out as well (trending downward from 8 since this algae started growing). I plan on dosing nitrate now as well, but no matter how many water changes and how clean I keep the tank, this algae just grows right back after being scrubbed away in about a week. I know the tank is very young and started with dry rock, but I have never had an algae bloom like this in my past tanks, especially when my nutrients were consistently in perfect range. I know there are a few stalks of typical bryopsis strewn about, but is this all just bryopsis, a different form of GHA than I've seen, or something totally different? I've just been keeping the tank stable hoping it would disappear over time, but I am thinking of taking more drastic measures at this point, maybe a round of fluconazole if this is a form of bryopsis. I appreciate any help!
