New Guy Here Needs Help!!! Pics inside!!

[CAMDIDDY]

Hello everyone Im new here to this site.
Ive had my 85 gallon tank setup for about 6-7 monthes now.
About 2 weeks ago I was given about 10 new fish, and stupidly tried to introduce them all into my tank. I have lost a few of them, and the ones remaining arent looking good.

Heres my current livestock & setup
85 gallon tank
2 Fluval 404 cannister filters
1 sea clone 100 skimmer (also have a corallife super skimmer not yet set up)
1 metallic foxface rabbit fish 7"-8" (white spots occasional brown spots)
1 large yellow tang 5"-6" (brown discoloration near tail)
1 claki clown 3" (dry looking skin/cracking, not eating well, shakes/vibrates violently sometimes)
1 domino damsel with same problems as clown
1 green chromis ok
1 blue neon damsel ok
1 coral banded shrimp ok
some hermit crabs & snails

There are also some white spots on the tank walls. What is this?
ph is a little low 7.8-8.0
ammonia 0
nitrite 0
nitrates 10-20
salinity 1.021
temp 78

They are getting worse everyday. Im affraid I will lose them all. Please help

I also have a 20 gallon sw tank set up that I can use. However it has a 6 line wrasse in it that could be infected with ich because a powder blue tang died from ich 3 days ago in that tank. also has a coral shrimp. Dont know how if there are any diseases in the tank, but wrasse looks ok.

Look at my pics and tell me what you think. thank you.

Nice Foxface, looks like ich. Remove all sick fish to quarantine and treat for ich and possible secondary bacterial infection. Shrimp will not withstand copper.

I have been to every pet store locally, and the only copper based mecication I can find is Mardel brand Coppersafe.
active ingredient is chelated copper sulfate
It says I can treat my main tank, just remove any inverts. Im thinking because I think most of species are infected, Im just going to move the coral shrimp to the 20 gallon, and treat my main tank.
what do you guys think?
also do I turn my skimmer off?
and what about bio media in my filters?

 

[CAMDIDDY]

Ignore the above post. I went ahead and put the foxface and yellow tang in the 20 gallon tank. I treated the water with the Coppersafe medicine. The tank is filtered with a Eheim ecco 2236.
Hopefully this will be enough. I need to know if I need any more aeration though.

As for the others they will stay in the main tank for now.
I know the ich is still in the main tank system, but I cant transfer them all into that small tank. Not sure what to do. All the other are fairly small damsels and the clarki clown.

Please give me any advice you may have.


here is the hospital tank. foxface's eyes look bad.

I moved some fish halfway across the country all the while they were in boxes for 3 days. When I finally got them out my tang started showing ich. I had them in a 30 long at the time, while I cyled my 120, he was in there with 2 cleaner shrimp and my puffer. The cleaner shrimp were on him every chance they could get and did a decent job but I went ahead and slapped uv sterilizer on there anyways. I made certain he was well fed with various foods and he snapped out of it in about a week. I think your best bet is to try a boost their immune system enough to allow them to fight it off themselves. There is a good chance the ich is still free floating in the display tank anyways so you may be wasting your time and money on isolation and medication.
