Help With My Coral

[NDIrish]

Params:
Nitrates 1
PO4 0
Ca 410
ALK 7.4
Mg 1350
Salinity 1.025
PH 8.2
Temp 78.6
Lights are 165w leds (3). 10" above my water. Coral are 9" below the surface. Blues 50%, are on 7am to 8 pm, whites 22% are on 12 pm tp 6 pm.

Params have been stable, very little fluctuations. Everything has been good. Then within the last week my purple staghorn is turning white at the bottom no signs of polyps. My ORA Ponape Birdnest is starting to turn white but I can still see the polyps. The staghorn & birdnest started where the light didn't hit them. My Orange Setosa Montipora is turning pink. The trunk of my Duncan was light green, looks like it is turning a dark color. I would show pics but the blues are on can't get good pics.
Tomorrow I plan on cutting the white parts of and reglue them.
What am I missing? Need help.

You need to raise those nitrates and phosphates. You are essentially starving your corals of nitrogen and phosphate

I started cutting my skimmer back a little at a time to try and raise them.
I feed my fish pretty heavy. All frozen food, LRS nanno, oysters, blood worms and plankton.

Raise phosphate, and keep it raised.
Use a phosphate supplement if you have to.

Dont be afraid to feed more your fish and coral will thank you. Your nutrients is low. I feed 8x a day on automatic pellets feeder plus some flake and 1 frozen at night

What would I need to raise PO4?

 

[Pdash]

Brightwell neophos, or you can make your own solution using food grade potassium phosphate or sodium phosphate.

I knew everyone would jump on that phosphate. How are you measuring it (hanna ULR, maybe)?

Is stray current a possibility?

Measuring with Hanna ULR. If there is stray current it's too low for me to feel.

Because it is by far and away the most probable cause of his issues.

An easy fix is neonitro and neophos as you can quickly reach your desired levels.
