Usually I only follow the instructions exactly when I have a very very injured fish.
Otherwise, I use the first initial dosage, but I dont keep adding it every day.
My fish still heal quickly, but i'm not having to load the tank up with it so much.
I dont think it's necessary unless you have a VERY injured fish.
Oh, and Malefix isnt really a Medication. I mean, i suppose you could classify it as meds, but really its Tea Tree oil. And its hard to overdose it.
Much different than Maracyn or those type meds. Malefix is more natural.
