You are just wasting your money if you follow the label in my opinion
the stuff is expensive at low temps. I would bring in a gallon or two
of pond water, heat it up over the stove to around 80 degrees or use an
aquarium heater. When the water is warm put it in a well lit place with
an airstone or just stir the water once in awhile. Add a teaspoon or
two of Lymnozyme/koizyme. I sometimes add an egg so the bacteria has
something to munch on. In an hour or two you will have plenty of good
guy bacteria to nuke the pond with. Water temperature is what will let
the bacteria reproduce quickly. I would not wait I think your smart
wanting to get the stuff in the pond to give the good guy bacteria a
head start. I have had other cultures where the label said put it in a
bucket in the sun for an hour and stir occasionly. This stuff with a
good filter is great!
