As Duncan said, Scrape is needed ASAP.

Meanwhile posting the test readings and a description of your gallonage, stock levels and filter type would be good.

Have to say I am not a fan of pond salting myself, it can limit the treatments you can do if you find the root cause of the problems.
No problem with salt baths and hospital ponds, but not the main pond - Sorry.

Problem is now there is salt in the pond what if you have White Spot, and need to use Machalite and Formalin. Or Costia...

You should really never treat unless you know what it is you are treating for. Salt is good for some things, but not in a main pond.

Let us know what the scrape said, and maybe there is a way around what you have already done.

Hi
just a thought, i had a similar problem all things looked ok with pond readings, my water supply carbon filter was not up to much and my local water company were upgrading all the supply pipe work which disturbed all the sediment in pipe work and put larger amounts of heavy metals into water supply, lost some fish untill changed all supply filters now ok.
