Loretta, The bacteria will disperse think of it like dye moves. It has a two year shelf life and just store where its dry as the water soluble bags dissolve readily with little moisture.In a pond less than an acre just get it wet it works. I apply it away from any outlet that is flowing. If I have a lot of outflow I cut the rate in half and apply evey 2 weeks instead.I will start my Febuary rounds starting Monday and appears I will have some serious ice to get thru in the non aerated ponds.
