Coralline algea and candy canes

Zoa_Fanatic · Jul 2, 2020

Hey reefers. I have a small candy cane frag with two heads. It has coralline algea growing on the plug it’s on. I am just now noticing on the places where the coralline is growing up the stalk the coral tissue is receding. The frag is doing fine and is open otherwise. Is the coralline algea hurting my LPS? And if so how do I kill it and stop it from causing my candy canes tissue to recede?

Do you have a picture? Coraline algae traditionally shouldn't harm your corals or climb like that on the skeleton.

You can see on the bottom there’s a small whitish area where the tissue has receded. The bottom part glued to the plug was hard skeleton that had no tissue when I bought it. I can take it out and scrape the coralline off with a pocket knife if I need to.

Parameters are:

salinity-1.025
pH-8.0-8.2
Nitrates- 15 ppm
Ammonia-0
Nitrite-0

32 gallon biocube LED. Tank is new but water and live rock and from my old 29 gallon nanocube which had been running for 7 years. I use 1/2 capful of Kent marine essential elements ans 1/2 capful of reef+ amino acids every week for stability and coral growth. This thing has been growing great. And the other side has some ages growth but no tissue recession as seen in this photo

The more I look at it I don’t think it’s coralline. I’m thinking now that I’m going to take the frag out and dremmel this crap off using a Dremel tool or scrape it off with a knife. It looks like it’s for sure what’s causing the tissue recession.

Sorry was responding when you posted your parameters...

It’s highlighted like coralline, you thinking cyano?

keep me posted in treated to know what it might be if not coralline.

I have 0 idea what it is. It looks like coralline in color but it’s not encrusting like coralline. And it’s clearly doing some kind of chemical warfare with my candy canes because they only receded when this junk touches them. I’m gonna Dremel this nonsense off and I’ll let you know if it comes back/my candy canes tissues keep receeding. I’ve got coralline on my trumpets and it isn’t hurting anything which makes me think this isn’t coralline just some strange color of different algea or purple cyano.
