FritzZyme 9 is formulated with specialized live nitrifying bacteria designed to minimize fish mortality caused by harmful ammonia and nitrite levels.

  • Usage Guidelines: For new setups, apply 4 oz (119 ml / ½ cup) for every 5 US gallons (19 L). In systems with heavy livestock, the initial dose can be safely raised up to 10x. For mature systems, use 2 oz (60 ml / ¼ cup) per 5 US gallons (19 L). This is a live product; avoid freezing.
