Microbenthic algal consortia are organized in multi layered structures that cover the surface of illuminated submerged substrates with a so-called biofilm. The ability of algae to produce oxygen in photosynthesis as well as their uptake rates of N and P make them effective components of any biological system. The organisms living in solar salt works constitute a biological system, which are able to aid or harm salt production. Systems aiding salt production maintain stable species composition and concentrations. They produce and accumulate sufficient organic matter to enrich the biota, prevent leakage and also increase the solar energy absorption. The natural conditions do not support more salt production and there is a requirement for the biological management. The naturally available organic and inorganic nutrients support the development of Dunaliella salina algal blooms that are benefit for solar salt heat absorption resulting in faster evaporation and an increase in the salt quality.
