How to Create Bright Pink Coraline!

[slingfox]

I do not believe this method is sustainable but I recently shifted the color of the coraline algae on one of my rockwork pieces from dark purple to bright pink. The first picture shows a closeup of the pink coraline. The second photo shows two pieces of rockwork, the left with the purple coraline and the right with the pink coraline.

How did this happen? I pulled out the rock on the right and poured 4 cups of boiling water over the middle portion in an effort to kill a small cluster of aptasia that recently appeared. When I put the rock back in the tank, the coraline was bright pink. I assume this means the coraline is dead and will fade away and get replaced with normal purple coraline again. I plan to enjoy the bright pink view while I can!

Not the best method, but whatever works for you.

My dying coralline also fluoresces pink and orange.

Yes, I do not recommend this method of getting pink coraline. It was just the side effect of my new battle against aptasia!

You posted on my thread about coraline algae and had to say I love the color on your rock and was hoping to get that and not all that purple covering 70% of the rock.

FYI absolutely love that OG in the center.

IME it will probably turn more white than pink. None of my tanks grow coraline well and I end up with light colored patches scattered around on the back wall.

I have that stuff in one tank. Its totally a different animal. It completely covers my frag racks. I do a citric acid soak and it will slough off in sheets but it's still a nice deep red lol. I have found my pin cushion urchins will eat it but I have too many coral they carry around so I live with it. I have 4 tanks running but only one has the stuff. I'm getting ready to move everything out of that tank and am curious if it will die off in a new system

Very interesting looking coraline. I have very small patches of that in my tank but thankfully it hasn’t taken larges areas over (yet).

My coral doesn't have a problem encrusting over it so I'm not really considering it a nuisance. Its been on the rocks for over 2 years but lately has decreased slightly. My N and P are running a little higher than they did the first couple of years when they were constantly at or near zero so maybe that has something to do with it but we'll probably never know. I've only read of a handful of people here talking about it.

Yup that's the stuff I was trying to get rid of some. Thanks for replying and saying coral have no problem encrusting over it. guess I'll get some favias or montis to put there and have to cover it up some. It's crazy how that's only in one of your tanks and not the others curious to know where it came from.
