Ok, so I have a 15 gallon with a clownfish, royal gramma, cleaner shrimp and cuc. I was having bryopsis issues, got rid of that but now I have green slime algae and red cyano in full force. Lights run from 10:00 to 9:00. I feed the fish every other day and reef roids once, maybe twice a week. I do a 5 gallon water change every week. I read 0, probably false negatives, on nitrate phosphate etc. the only thing I can think is I added unfurled dry rock 2 years ago and maybe it’s still leaching stuff, but that was 2 years ago. I do use chemiclean and vibrant but it’s been relatively ineffective. Any help on how to get rid of this stuff would be appreciated!
