The cold water, anything below 65°, has an impact on the ability of the chemicals to dissolve properly. I would recommend using liquid chlorine if you have to shock in lower temperatures. You can dissolve granular shock in warm water. Perhaps it will work if you completely dissolve it before adding it to the pool.
