from a friend i might try this
as an update i just got a 30ml bottle of 100% pure tea tree oil (equiv to 3L of melafix) at the pharmacy for 12 bucks and they threw in a free 3mL syringe with 0.5mL graduations
if you dont feel like premixing the 1% mixture, u can use a dropper, 1 drop per 10 gallons of aquarium water (20 drops in a mL, 5mL x 20drops/mL = 100 drops, therefore 1 drop is the same amount of active ingredient as 5mL of melafix)
does melafix just heal fins our does it kill stuff that can be on the fins too?????????????
