I have an established asd rainbow colony about the size of a grapefruit that was pink and had green polyps. Recently the colony has turned green and lost a lot of the pink coloration. It still polyps out nicely and looks very healthy. None of my other other corals have lost or changed any color. I did an ICP test and everything seems to be fine except I was a little low in iodine.
The only major change was I switched over to a kalkwasser reactor for my all/calc needs.
Any thoughts on why it has turned green? Any suggestions on how to get it back to original color?
