Formalin pre qt dosage/time

You would need to read the bottle and it will tell you either a prolonged bath dosage or a dip. I can't remember off the top of my head how many drops per gallon for a dip, but the dip should last 50 mins
 
For 37% formalin you want to use 20 drops per gallon. Bath should be 50 min max. I usually do 40-45. Remove sooner if the fish seems stressed or not handling it well.
Make sure to airate the water prior as well as during the entire bath.
