The study applied qualitative and quantitative phytoplankton analysis as a tool for determining algal community characteristics and identifying the directions and general trends of changes caused by the restoration of Lake Głęboczek through phosphorous inactivation before and during its application. The method applied in the studied lake aimed at reducing phosphorous availability through the chemical precipitation of its excess mineral forms in the water body and limiting their mobility in the bottom sediments. Restoration efforts led to shifts in the phytoplankton domination structure followed by the inhibition of blue-green algae development. In consequence, a significant decrease was recorded in the growth rate of the phytoplankton community.
