[10] Keeping the pH in a suitable range (5.0-9.0 for freshwater systems) is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO 3) or sodium hydroxide ...

In 1951, the Reorganization Act elevated the Division of Fish and Game to the Department of Fish and Game (DFG).
