Coral trouble

[Noob_reefer]

My tank is 10 months old everything was growing fine until I started noticing certain corals losing tissue. Some white spots started appearing on my monti first. Now today I noticed my litho has these white spots as well. It's weird because only the encrusters seem to be taking a hit.
Parameters: nitrates 5
Phosphates ? I have a nyos kit but I run gfo, and chemi pure.
Salinity 1.025
Mag 1410
Ph 8.2
Calcium 460

What are your phosphate levels? Have you changed anything recently? Also, do you know your magnesium levels?

My local fish store tested the phosphate and they couldn't detect it. I haven't changed anything recently other than adding more coral. I know that my phosphates were pretty low before

Alkalinity?
Since your running Chempure Elite I would pull the GFO

My alkalinity is at a 10.4 I have a hanna checker

Yea I might do that and see how it goes. I ran both because I had a hair algae issue a couple months ago

You need some phosphate for SPS. They won't tolerate a lot, you just have to find that happy place for them.

Ok, but is there a reason for the encrusters being affected or does it come down to them being the first to show signs

They are SPS and have different requirements

Drop your alk slowly is my suggestion. With low no3 and po4 you want lower alk so you dont burn anything. for example I always have super low no3 and po4 no matter what I do and keep my alk at 8.5. From everything I have read you want alk 8-9 with low nitrate and phosphate. Drop it over a week or two. Just a suggestion

He said he had a wrase right well I thought some wrases were not coral friendly could it be eating the coral since they are losing tissue

I have also heard of crabs eatjng coral as well have you ever witnessed it

My wrasse is reef safe, unless it's a hermit or nori

I did have some emeralds go rogue but they picked at euphyllia and my duncans

Ok

Ok so my course of action will be to drop my dkh to 8-9 due to my low nutrients and take out the gfo and leave the chemipure and carbon
