Hot pink coraline algae

[Lavey29]

Many months back I seeded the tank with that bottle coraline stuff. I used purple and hot pink. The purple flourished and is spread throughout the tank but I never saw any bright pink until a few days ago. It's on my plastic and a few frag bases now. I hope it takes off also. I did notice a little more calcium drop too. Will the purple outcompete the pink or can they both flourish in the tank?

IME, hot pink coralline is dying coralline. I only see it in my tank where the coral base is growing and it kills off the coralline as it does this, turning it hot pink for a day or two.

+1 dead or dying coralline.

Yes, I would agree with this except I specifically seeded hot pink and also the places it is forming have no existing coraline there to die off.

Actually now the return pipe plastic is turning more purple again. I guess when I did my water change the air must have bleached the purple to pink while it was exposed out of water. Now it seems to be turning purple again on that part. Strange though my powerheads on the side come out of water to for cleaning and the corline on them never changes color in the dry air. I have little bright pink specs on some bottom rocks to but no existing purple coraline there....wierd

if i recall correctly, i saw somewhere if coralline algae is exposed to air, it will turn hot pink and then ultimately die off. not sure of the validity of this, but it did happen to me when i exposed a coral frag out of water for a few minutes.

I used to have a distinct line on my tank where the coralline algea died where it was exposed to air when my return pumps was turned off, so I know being out of the water can kill coralline.

When mine is dying however I would describe it as more of a fluorescent orange than pink.

Yea I'm guessing mine was air related now but both MP40s are out of the water to during water changes and look at them. The white is from urchins chewing on them.

Well some of my hot pink spots that got air exposed have turned purple now.

Oh well, I was never a hot pink kind of guy reefer anyways....

I have used the purple and pink helix in the past and my experience has been that the purple will dominate but the pink will pop up and grow witch adds some nice contrast. The pink will be less than 10% from my experiences though.
