I am trying to make my own (bait oxygen tablets), used for fishing to keep your live bait minnows alive, to sell at my dad's bait and tackle shop. I have found that it is possibly a chemical composition of (strontium peroxide, calcium sulfate, calcium monophophate, and manganese dioxide), and that they all come in the form of powder. So, what I am wondering is? (1) Does all of the following sound correct (2) If so , what would possibly be the ratio percentage of each (3) Or where might I find any helpful information. The objective is for the tablet to create air bubbles when dropped in water. Thanks, I will be checking back to see if anybody can please help me.
