I have a CB Pink Dreams chalice that has slowly been changing its color. It lost its green rim, and is now a brownish maybe purple? The bright orange and pink eye has started to diminish and looked brown too. I'm wondering what I can do to change this or what may have caused this? I have several other chalices and all have great color and growth. Parameters are stable. Alk and Mag are a little high, 10 and 1500+, but have remained very steady. I have it placed at the bottom of my tank with very low flow. Thanks for any input!
