✦ Synopsis

The phytoplankton productivity over two years in a lake heavily loaded by acid mine drainage was very low . Algal assays indicated that below pH 5 .5 the water, if buffered and fertilized with phosphorus, resulted in log growth . Above pH 5 .5 algal log growth could be induced with phosphorus addition only . However, an in situ bag experiment was done in the lake and immediate bloom conditions of the indigenous algae resulted from phosphorus addition only, despite pH values below 5 .
