Coraline question?

[eric31887]

Have noticed my coralline in my tank is going from purple to a pink color but everything in my tank Is doing fine and the corals are opening as big as always? What would it do this?

Have you checked your Ca levels?? Also it depends on your lighting and the strain of corraline you have in your tank, So many things that can effect the color and growth JMO

Might be a different strain also. Mine changes all the time between several different colors on my back glass. One strain will become dominant for a while and the another one, and another, then maybe the original one. Mine change up between pink, purple, dark purple, green, sometimes red. It's pretty neat to see over time actually.

Sent from somewhere using something.

check alk. I've had mine do that when my alk went out of wak sort of a canary in the coal mine.

Right it may be a different strain taking over. Coralline prefer different lighting levels with most preferring lower light levels. The ones that prefer higher light levels are usually slower growing. If the actually strain is changing color it could be dieing from change in light or it could be low calcium, mag, or alk. Never know too it could be turning pink because its doing better.

The culprit would be asterina stars! Look real closely and you will see one hovering close by a small patch of it....It will turn pink then day or so later it will turn white..
