in a closed bag the ammonia builds up fast driving pH up, but the fish are using
oxygen putting out CO2 and that drives pH down so ammonia is less toxic. open the
bag and the CO2 is blown off, pH jumps fast and ammonia is toxic.
not to mention, when Jo Ann opens up the bags she found very very early on that
putting tank water into the bag resulted in something very foul smelling coming out.
so it just isnt a good idea to open the bag before the fish is going to be moved out.

That was an interesting chemistry lesson. Thanks
