Tang went white overnight? (Disease?)

[Reef noob_]

I dosed my 90 gallon tank (150g total volume) tank with flatworm exit around noon yesterday.

The product worked as intended and I followed the instructions properly, running a full reactor full of carbon as well as a bag full in my sump.

All of the corals were visibly upset yesterday so I did a 20 gallon WC, which is the most I can do at one time. Im doing another currently.

This morning, I noticed that my yellow Tang which I have had for over 3 years in this tank has turned partially white and is breathing heavily and hovering in one spot. He's looking pretty rough. (Photo attached)

Not sure what else I can do but keep on replacing filter socks daily and doing more water changes. The carbon is still going and I would assume it has taken anything out of the water by now.

I'd appreciate some help on this.

I have heard the the Flatworm Exit can nuke a tank, too much die off, can you do a big water change, place air stones in the tank?

Currently doing a much as I can to export.

Changed filter socks twice yesterday, once today so far.

Cleaned skimmer cup wife yesterday, once today so far.

Did 20g water change yesterday, currently mixing 20g for today.

Not sure air stones would make a difference with the large skimmer im running (vertex Omega 130)

Looking for some way to maybe neutralize the chemical released during die off. Running UV wouldn't help I assume and I don't think changing the carbon out will do much...

New carbon.

New carbon.

Just replaced the carbon in my reactor.

After the water change things seem slightly better but many corals are still struggling and the fish seem unhappy. Some corals are nice and extended however. Weird.

Pretty much everything seems to have either bleached or browned out.

During my water change I noticed that the salinity was way down at 1.022. I adjusted it with the replacement water up to 1.023 and will slightly adjust higher with daily WCs this week.

Run carbon so it can remove un want chemical out of your system, also it will need to replace often

Woke up to a dead Tang this morning. I haven't seen either of my wrasses in 36 hours now so they're either hiding or dead as well.

Im currently in the process of doing another water change. I already replaced the carbon and filter sock as well as have cleaned the skimmer today. Really thought I was over the hump yesterday after seeing coral further extended.

How many flatworms were in your tank? They release toxins as they are dying, and if too many died all at once the carbon might not have been able to keep up with removing all the toxins.

I try to remove as many as I can before dosing Flatworm Exit. With the aquarium lights turned off, point a bright white light (e.g. flood lamp) at the front of the glass and use airline tubing to siphon them out as they congregate by the light.

There were definitely a lot, but nothing crazy that I thought would nuke the tank like it did. Going to continue with twice daily water changes and carbon and hopefully bring it back around. There's no other way to get the stuff out?

Looks like a massive ich breakout.

Water changes and running carbon.

As far as your flatworm problem goes, adding a natural predator (e.g. Pseudocheilinus or Halichoeres wrasse, Springer's Damsel) might be a better long-term solution.

Is the fish still alive?

Thanks for the advice. All other fish are out and looking healthy after 2 sets of water changes today. Will change out carbon once more tomorrow morning and nurse everything back to health. Lost a few across and quite a lot of montipora as well.

My Tang died overnight yesterday but the rest of the fish should be pulling through okay. For some reason the toxins seemed to affect my Tang much more quickly and intensely than the other fish.
