Pink montipora turning light pale pink

[Charlie’s Frags]

The problem with this is if this is nutrient deficiency along with higher alk and you were to add light intensity it will make the problem much worse. Need to know po4 at a resolution of .00 ppm phosphate first.

I recommended lower alk first. I doubt 0.00 on Red Sea test kit is true 0, but you’re right, higher light and 0 po4 is bad.

Are you sure that is a Monti Cap? It looks more like a Pavona Maldivensis they prefer lower light levels.

Either way it's starving (bleached). Up your nutes and or lower the light level.
