With the simple addition of a bag of EM ceramic pipes that contain beneficial micro-organisms baked within the clay, these help to prevent the rainwater from stagnating and keep the water fresh and disease free.
EM Ceramics are a natural, non-toxic Water Butt Treatment that has a continuous effect, preventing the water from turning stagnant. A bag of the specially produced ceramic pieces are simply placed at the bottom of the water butt for it to take effect.
If you're a keen gardener and may have numerous water butts, or you might just own one to collect rainwater for use on the garden during dry periods. And whilst stored rainwater is a better form of water for plants than tap water, due to the fact it doesn’t contains chlorine and other chemicals, it has a habit of turning stagnant and horrible smelling when stored for a long time, especially during hot weather.
