Live Rock turning white?

[Mzam]

I noticed a few days ago that my rock started to turn white and I was little concerned but didn’t think much of it till I noticed today it’s spread all over the whole aqua scape. I lowered my lights a little bit a few days ago but it still continued to get worse.

It’s a 25 gallonwith mostly lps and soft corals. There’s a small scopas tang, 2 clownfish, a royal gramma, a pacific cleaner shrimp, a couple emerald crabs, and about 15 hermit crabs a snails combined.

Welcome to R2R! As mentioned above, some pics using white lighting will be the best help.

Nitrate of 40 is a tad high, throw the nitrite test in the trash, and purchase a phosphate test as it's an important one also.

Are you saying the coraline is dying?
Check and double check your specific gravity.
How are you testing it? Check it again.
