Algae ID

[DHill6]

It was maroon in color until I tried peroxide on it. Now it’s pretty pink. Doesn’t pull off rock. What type and how to get rid of it? I’ve dosed Vibrant in the past for bubble algae. Last checked p04 was .07 on Hanna ulr. Running skimmer and mesh sock, changed out frequently.

Perhaps a kind of Gelidiopsis? I've found emeralds will pick at it
