The Sera NH4/NH3-Test is a tool that allows monitoring of the ammonium/ammonia level in both fresh and marine water, which mainly arises from fish waste and can be harmful to fish. It helps determine the total concentration of both substances, and the actual ammonia level can be calculated using the included chart. If there is a risk of danger, the Sera toxivec or Sera pond toxivec can be used for help. Sera bio nitrivec, sera marin bio reefclear, or Sera pond bio nitrivec can be used to actively fight against the lasting enrichment of these substances. The product is sufficient for approximately 60 measurements.
