SPS CORALS STARTING TO DIE HELP

[itsnicholas]

Hello, I have about 24 SPS coral mini colonies and frags. All of a sudden over the course of about 3 weeks I first started to see my Fox Flame coral start to bleach a little bit and then more and more corals starting to bleach in weird places. My water parameters are fine but I believe there are some type of worm or pest eating away at my corals. I took some pictures of the corals that are starting to bleach under white lights. Not every coral is showing these signs. Most of them are doing just fine.

I would post your parameters and set up just because. The holes look like something was eating it though

How long have you had them?
Better yet question, how long have you been into sticks?
How old is the tank?

My water parameters are fine

What is fine?
List everything you know parameters of.
Include par and flow of you know.

but I believe there are some type of worm or pest eating away at my corals.

This doesn't look like pest to me.

I took some pictures of the corals that are starting to bleach under white lights. Not every coral is showing these signs. Most of them are doing just fine.

I'll look for your response. Please include a full tank picture.

My guess is, nutrients are too low. Or some type of acro bug. They r super tiny and really hard to see. Could also be unstable parameters. Warm water temps. High DOC. Do a ICP and see if there’s some other issue like high metal percentages.

Even under what looks like daylight, those acros are very dull and have very little color. Best bet would be to give us a full breakdown of alk/cal/mag/NO3/PO4, dosing, lighting, flow, etc so that we can help a bit better.

My bet is on tanked PO4.
