Help with receding candy cane coral

[edikpok]

The aquarium currently has a clownfish and midas blenny (been there for 3 years) and a new cleaner shrimp (boxing day addition). The problems started before the adddition of the shrimp though.

Should I consider a Loguls dip? If so, what is the best practice for the dip?

Forgot to mention that around the same time that the receding begun, there was also a sudden outbreak of red slime. I used chemiclean to rid of it. I used it once before with no ill effects...

Anthony- the original candy cane actually came from you about 5 years ago I bought 2 heads back then of this neon green candy cane.
