Hey all. Does anyone know what type of algae this is? and more importantly how i can defeat/get rid of it? it is purple and looks like turf. The only way i have been able to get it out is to use frag clippers and cut the coraline algae out. the purple algae is embedded in the coraline. so i cant just pick it off. i feel the more i try to cut it out, the more it multiplies since i cant get all of it as it floats away. plus i knock into too many corals breaking them. It is starting to multiply and irritate corals near it. Any thoughts would be appreciated. thanks!
