Unfortunately, many microorganisms are capable of thriving even in the concentrated salt water of a solar pond. These microorganisms can thrive near the surface in the wind-mixed layer, or in the halocline of the pond. They can also thrive, and attach themselves to, nets floating on the surface of a pond which serve as wind-breaks and which suppress deepening of the wind-mixed layer. Attachment of algae to the nets decreases the buoyancy of the nets and can cause them to sink, thereby reducing the effectiveness of the nets. The presence of algae on the nets also decreases light transmission through the nets such that the efficiency of the solar pond is reduced.
