I appreciate you guys taking a look. Wish I had better pics or a microscope to help identify. Whatever this is it keeps hanging around. Mainly on the back wall (poly), wave maker, and the return nozzles. But it has been attaching/growing on my Stylos, Birdsnest and other hard corals. Causing the polyps to retract and seems to be inhibiting health.
Tank parameter: PH- 8.0, Alk- 9.4, Ca- 430, Mg- 1300, NH³/NH⁴- 0, NO²- 0, NO³- 10, PO⁴- .08, Salt- 35, ORP- 327, Temp 78
I scrape and scrub with weekly water changes. Tank has been maturing good and maintaining stability. It's a 28g and about 8 months old.
This appears to be dark brown in color and moves like algae. What do guys see and how do I combat it?
