Montipora browning out

[djryan2000]

I have a green monti that is browning out. No other monti is, even the orange one glued to the same plug, but it’s certainly not as colorful as when I bought it. My nutrients are 5ppm nitrates and 0.14ppm phosphates. Is this indicative of me needing to bump up my lights?

"Probably" it might also indicate a bacterial infection or excess UV as melanin is used by corals to combat bacterial infections and too much UV light.

Thank you! No other coral is browning, despite me having 3 other monti pieces receiving what I think is similar light. Should I take this as a bacterial infection? Do you know how I can tell the difference between the two?

Keep in mind immune systems will vary not only at the species level but also the genotype. Unfortunately we can't test for bacterial infections. If most of your corals are doing well I wouldn't be changing the lights just for one specimen. If possible find out what the monti in question grew under then check your system and move accordingly.
