Melafix bad for bettas?

I wasnt disagreeing, my boyfriend bought a large bottle of melafix and diluted it for me. I would never use a melafix bottle to dose unless I had a syrange. Bettafix is a better alternative.
 
I can see the being difficult in a smaller tank...I was keeping mine in a 10 gallon so I could just do 1/5 tsp and call it good :P
