Do have a question for everyone. The transition tank is starting to have some corals look poor in it. Our giant Pink Monti, the Idaho grape monti look faded. A few favia, and acans are fading, and a cluster of daisy polyp are looking rough.
Most things look great still, acros look great.
I tested tonight.
PO4 - (0.0-0.02)
NO3 - (0.0 - 0.25) but closer to 0
Calcium - 530
Alkalinity - 14
I know calcium and Alkalinity are high, but those are not off the chart.... I slowed the drip from the calcium rx.
Anyone have any ideas? Should I be more concerned about the calcium levels?
