Birds nest located between two power heads going white from bottom

[DUMBO]

I’ve been doing regular water changes but slowly watching this beauty turn white. Any suggestions?

What are your parameters?

Parameters, lighting, are you dosing anything?

What are your parameters?

Alkalinity 169ppm
Calcium 558ppm
Phosphate 2.18ppm
Salt 32.3
ORP 343

Light: Aquatic Life HALO Saltwater LED
Coral is directly beneath it.

Not currently dosing anything.

What about nitrate and mag.

Magnesium 960ppm
Nitrate 40

Nitrate 40

I'm not a number chaser but I'd imagine those two probably aren't helping.

That's some crazy high phosphate.

And also in my experience birdsnest are very good indicators of alk swings and or nutrient swings. They will die from rtn when one or the other happens. Fragging it up and keeping things stable have worked for me when I have had to save them.

So it seems between your low salinity (32.3 ppt = 1.024 sg), low mag, and super high NO3/PO4, you've got a couple different things to iron out and see if it helps. I'd work on slowly raising the salinity up to 1.025 and bringing your nutrients down and seeing if things change

This. Just lost my Neon Green because of a spike in nutrients. Nothing else effected and wondered what could be causing this. The only thing that changed was I went from biweekly wc's to once a month. When I tested the nutrients NO3 jumped from 5 to 50 and PO4 went from .02-.05 to .15-.25, I'm presently working on bringing those down and have gone back to biweekly wc's.

I do weekly water changes, but I feed my sps every other day. I also run phosgaurd

That magnesium is pretty low as well. I try to hover around 1380ish. I would be way more concerned about the nitrates and phosphates, but as a secondary goal raising that mag wouldn't hurt

Thanks so much for the advice, I’ll get to work!
