Thanks texreefer. Exactly what I wanted to know.

I was also wondering if the Bionic expires? If so how long is it good for? Would keeping it in the fridge help it last longer?

I ask because I have a small tank, 12g and no sps or anything that would use up the elements quickly. I also am going to have to wait a while to use it I guess since I cant buy $40 worth of test kits anytime soon. THanks for the input.
