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 (NaOH). A low pH will lead to high levels of dissolved carbon dioxide (CO 2), which can prove toxic to fish.
