Your thoughts?

I have a 210g aqueon all glass system with an eshopps rs300 sump
Lightly stocked with approx. 90lbs of live rock 150 lbs of live sand I don't dose anything I do 60g water changes every other week.
Parameters are as follows
Calc 440
Dkh 7
Phos 0.5
Nitrate 0.5
Amonia 0
Nitrite 0.5
I thought the reading from my test kit were off so I had my LFS check my water and everything tested good.
I had the following fish in my tank
1 panther grouper 5"
1 Niger trigger 4"
Coral beauty 4"
Koran angel 5"
3 yellow tangs 2"
1 maroon clown
And an orange spot goby
I lost a tang and thought the bigger more agressive fish were picking on them so I re homed the grouper and trigger. Next day the koran died then two weeks later the tangs died. Noone had any signs of illness. A week ago my coral beauty died. This fish looked as if something had eaten his side...I still have the clown and the goby and they show no signs of disease, but I don't want to kill anymore fish afraid to add any even a damsel. I have added an apex classic for more control I was getting temp swings in the 4 degree range but now I'm a stable 78 to high 77. Salinity is at 1.025
And the top off stays full

Any advice?
Sorry for the rant this was supposed to be short and sweet..
O btw the tank is almost a year old was fowlr converting to a softie tank
Thanks

If you really have nitrite in the tank that seems to be the problem

After a year your aquarium having Nitrite ,means you could be your adding it accidentally from your 120 gallon a month water changes ? Are you testing and filtering (r/0 filtering your fresh water ,or RODI even better,before mixing it with salt.)
The LFS tested your water and said your parameters were good,so I don't know for sure Nitrite ,is the problem.Try retesting your aquarium water,to update your readings.

I have not tested it...I'll test it today and see what I come up with

I use a 3 stage RODI system by coral life that has new membranes. Taking a sample to the LFS tomorrow to have it checked I took a pic of the fish and sent it to the LFS they say looks like something was picking on it....

But he was after I took the trigger and grouper out the biggest fish in the tank.

No white spots? Looks like he was rubbing himself up against the rock. Maybe velvet? I heard it can take fish out pretty quick without showing outwardly symptoms..

 

[Johnnybgood74]

No spots he was eating good and social...

Sounds like it is time to hit the pause button, and remove the remaining fish to quarantine - you shouldn't be testing positive for any nitrite in your tank at all. However, it could be some other fish disease as well. I'd remove the remaining fish to a small quarantine system and see how they do, give the DT time to fallow and get its water parameters back in line. Run a healthy course of carbon just in case.

At the LFS now they are testing everything and it's all normal...no nitrite Amonia he says actually have pretty good water the Dkh is a little low but so far that's all he's found I'll update when all tests are done

Sooo I need to start kalk Wasser to correct the parameters and go fallow it would seem I have a parasite in my tank [emoji22]

Yes, if no nitrite then you have some kind of pathogen. A 10g would be sufficient for the clown and goby - however, start with new saltwater, and don't transfer over ANYTHING (rock, sand, etc.) from the DT to the smaller tank - get some bacteria booster, as you'll need to create some biological filter quickly, or need to do large water changes reqularly, or both. Observe the fish and be ready with some medications should the need arise. Be aware they possibly already have whatever claimed with other fish...

Super confused....the LFS says there's no need for me to move anything...if there was something in the tank the other fish would have died or gotten sick, He seems to think the coral beauty was injured and the injury got infected....I'm thinking a move might be in the best intrest just in case?

That looks like it could be possible ammonia burn or uromena.
