Hello. under blues there is a red glowing matt of this stuff on my sand bad, localized to the back left of my tank under whites they look kinda brown pinkish. I tried to siphon it out and add a powerhead to see if this work, if anything it made it worse haha. My test is as follows
Salinity: 1.027
PH: 7.89-8
Temp 79
Alk: 8.67
Cal: 436 (shop says it 457)
Magnesium: 1503
Nitrates: 1
Phos: 0.079
Ammonia/nitrites 0

The tank isnt the cleanest, especially the back and side glass as shown in the picture but I do have a fuge with lettuce in there as well as a fuge light. my lights are on from 9 am, peaks between with whites on for a few hours then blues from 3-6 then the lights turn off.

I feed my tank once a day in the morning with frozen Mysis and a small piece of dried seaweed for the tangs

It does look worse than the picture btw.

Here are my inhabitants
Sailfin tang and Scopus tang
2 Clown fish
six-line wrasse
Midas blenny
Lawn mower blenny

My tank is a redsea 525 XL, all the coral looks fine and happy otherwise, attached pictures.

Scrub rocks with firm toothbrush and siphon uo
Reduce white light intensity and add snails such as margarita, trochus, and nerite
