I live in EU where fish medications can be hard to get by. Therefore i treat most issues with salt. The question is:
Can i use salt for water treatment systems in fish tanks?
From what i see, it is pure salt although a bit larger crystals than regular salt.
I have been using salt for ponds up til now, but it can be hard to find, especially during winter seasons, and also fairly expensive compared to filter salt.
Not really. Most fish tolerate some salt, although it varies from types to types.
In my case, it is for goldfish, but this is for treating issues such as fungus, bacteria or parasite infections. I use 3 grams pr liter so it does not change the water into salt water as such. Just raises salinity enough to fight fungus and some parasite as well as heal wounds faster, with less chances of bacterial infections.
The question is more about what types of salt can be used, not if salt is usable
I understood you shouldn’t use tablesalt due to additives (anti clumping) and ionization.
Take this with a grain of salt as I have not looked into it further.
I’ve heard that too, but took it at word value. I did a quick research and it seems like it is not as dangerous as one would think. The concentrations are far smaller than when considered dangerous to fish. The post mentions that there are no researches for what the effects of so small concentration over longer periods may have, but to be fair, i usually only treat the fish until symptoms pass - this usually is a week or two.

Which concentration did you use?
I use 3 grams pr liter for treatment or 1gr pr liter for precautions
Thanks
Note that most plants dont like salt though. So if you have a lot of plants, maybe set up a treatment tank
Good advice. Yes, I have a lot of plants, snails and shrimp. A separate treatment tank is a good idea.
