Hello All! I have been having this weird algae growing all in my tank. My tank is 4 years old, nitrates are at 8.0 and phos are at .05. I added/plumbed a 50g frag tank to my 90g display about 2 months ago and thats when I stated seeing this stuff. I read alot before adding the frag tank to make sure nothing would happen. It may be a coincidence but it wont go away. I do 1g wc every night and 15-20g every month if needed. Any idea what it is and how I can get rid of it? Its on my corals. It looks like Dinos but not sure

thank you!

pics aren’t the best but its a brown/red ish color. its hard to describe IMG_2309.jpeg
