Recently Ive noticed some of my acros suddenly start to die. Always seems to start at the tips and works its way down. I actually thought it was my swing in salinity but its been 3 weeks since thats been corrected. Ive been looking at threads about these pest. I haven't seen anything on the acros but I know they are tuff to see. Water parameters are fine now or could this possibly still be corals recovering slow from the salinity swing ? Salinity jumped to 1.28 at the time
