I have a 240L tank
Temperature is 25 degrees
Other fish with it is- neon tetra,guppy,shrimp assasin snail, hillstream loach

It’s around 2 and a half years old

I have neon tetras in my 240L tank with a fluval 305 filter.
For some time there has been a slow growing white patches on its scales.

I used my 10L quarantine tank with esha 2000 which has not helped.

How much salt do I use per 10L for the neon tetra
I am planning to do it for a day but idk how much salt to use. ChatGPT,Google and other websites have different advice.
