Why would you want to take such a risk with a living thing? They may only be fish, but they are living breathing things. Your care for them should not be taken lightly. That's like saying, "I'm going to have a baby. Now I know that drugs and drnking is bad for pregnant women, but if there's a chance the baby will be OK then I'll drink and do drugs anyway...."
Just cycle the water with a piece of raw shrimp. Same effect, and more responsible...
