Finally got a better microscope to help take a photo of the bane of my existence. This algae has been a persistent pain in the rear and nothing in the tank seems to go after it, including: tangs, turbo's, trochus's, hermits, or my urchin. It appears to come in looking like normal green hair algae, but quickly turns a dark brown to the naked eye. I have done multiple 4 day blackouts with no improvement, two separate reflux (Now finished a third dose of reef flux, this is not species of Bryopsis) and chemiclean treatments with no improvement, removed all whites from lighting with no improvement. The algae has a reasonably strong foothold and takes a bit of effort to remove and does not seem to respond to lower nutrients either. I got a little big for my britches and tried to setup an auto dose on trace elements including IRON and the algae absolutely blew up. Just wondering if anyone can help ID this thing and give me some general advice; thanks.
Phosphate is holding around.07ppm (ICP verified)
Nitrates have been at 6-9ppm for 6 months (ICP verified)
Silicates/Silicon 0-RODI and 127.8 µg/l in the tank.
Turf Scrubber running 12 hours a day growing the same nasty algae that's in the tank but hasn't made a dent in the crap in the tank.
