Any fishkeepers able to give me a definitive answer to how much formalin I need to put in my fish tank to try and cure a case of white spot (Ich)?

I have a small fish tank (biorb) that holds 30 litres. I recently bought some new fish but noticed white spot on one of them and borrowed some formalin from my mother. Unfortunately there aren't any instructions with it. I looked on various websites but I keep seeing various ranges and dont want to kill my fish!
The formalin I have is "pure" i.e. it is 37% formaldehyde mixed with methanol and doesnt have any other ingredients with it.
The fish are 6 small platys in a tropical set up.
