I'm looking for help from fellow reefers on getting rid of my algae problem. I'm not entirely sure what algae I've been battling fort the past 2 months. I'm pretty sure it's not just one kind. I keeping getting brown algae on the glass that easily wipes away. I don't see any bubbles so I'm guessing diatoms. I replaced all RODI filters and have done 3 water changes over the past month. It keeps coming back but with white lights it actually looks green and not brown.
Second...I had green algae on a few of my rocks that my Tang and urchin wouldn't touch. It looks like hair algae but, I was guessing bryopsis since nobody would eat it. I manually removed as much as possible. It's still there but doesn't seem to be getting long.
Third, I had what looked like green cyano on my rocks. It all blew off with a turkey baster.
My parameters all seem to be fine but, I lost a cleaner shrimp, my Duncan keeps closing up, and my urchin is slowing down and losing spines. But all other soft Coral and fish are completely fine.
pH -8.1
Ammonia - 0
Nitrite - 0
Nitrate - 6.8 (was 11.5 a month ago)
Phosphate - 0 (took GFO out to try to raise a little).
Any ideas on what I need to do to get this under control?
Thank you in advance!
