WARNINGS

This kit measures total (NH3 and Nh5+) and free ammonia (NH3 only) down to less than 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia Nh5+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system. This kit is based on the same gas exchange technology that is used in the Ammonia Alert and thus is the only kit on the market that can read levels of free ammonia while using ammonia removal products such as Prime, Safe, AmGuard and any similar competing products. The other kits (salicylate or Nessler based) determine the total ammonia by raising the pH of the test solution to 12 or greater. At this high pH all ammonia removal products will breakdown and rerelease the ammonia, thus giving you a false ammonia reading.

This kit measures total (NH3 and Nh5+) and free ammonia (NH3 only) down to 0.05 mg/L .

Free ammonia test

Fill sample pipette to base of bulb and dispense to a test cavity of the test plate.
Unscrew the cap from the sensor container and remove a sensor using the supplied forceps, rinse with clean water, and place in the test cavity containing the sample. To avoid damaging sensors, do not handle with bare ﬁngers. Use the supplied forceps to manipulate sensors. Avoid excessive pressure.
Read after 10–15 minutes from bottom scale (less sensitive) or after 30 minutes from top scale (more sensitive) in mg/L.
On completion of tests, rinse sensors, and return to their container where they will regenerate within a few hours.

Total ammonia test

Fill sample pipette to base of bulb and dispense to a test cavity of the test plate.
Unscrew the cap from the sensor container and remove a sensor using the supplied forceps, rinse with clean water, and place in the test cavity containing the sample. To avoid damaging sensors, do not handle with bare ﬁngers. Use the supplied forceps to manipulate sensors. Avoid excessive pressure.
Add one drop of Total Ammonia Reagent.
Read after 10–15 minutes from bottom scale (less sensitive) or after 30 minutes from top scale (more sensitive) in mg/L.
On completion of tests, rinse sensors, and return to their container where they will regenerate within a few hours.

Reference testThe proper performance of this kit may be validated by running a total ammonia test in the normal manner except that the reference sample is used in place of a aquarium sample. It is not necessary to run a reference test to use this kit. The only time you might choose to run a reference test is if you have cause to believe the test is giving incorrect results. If you run a test using the reference sample and obtain the correct result (based on the known reference value provided) then you know the test is giving correct results. To run a reference test use the Total Ammonia Reference as the sample in a total ammonia test. Reference value is 1.0 mg/L.
Hints: Readings before 15 minutes or low ammonia concentrations may show an uneven color or a darker color on one side of the sensor. The correct color is the darker shade. If color response is off scale, run test on sample diluted with distilled water. Dilution may be prepared directly in test cavity: for example, use 5 drops of sample with 5 drops of distilled water, multiply result by 2; use 2 drops of sample with 8 drops of distilled water, multiply results by 5, etc. The sensors are small, yellow discs and may occasionally stick to the container lid. In rare cases, the blotter paper in the sensor container may get wedged to the underside of the lid and will hide the sensors; simply remove the blotter paper with the forceps to reveal the sensors.
InterpretationThis kit may be used with freshwater or marine water. Unlike other kits on the market, the chemical basis for this test assures that interference from other substances is highly unlikely. The values reported by this kit are expressed as ammonia, not nitrogen. To convert to nitrogen multiply by 0.82. Ammonia is toxic and should be undetectable in any well-established aquarium. During cycling (i.e. initial aquarium set-up stage), it may exceed 20 mg/L. Ammonia exists in two forms, free ammonia (NH3) and ionized ammonia (Nh5+), in an equilibrium dependent on pH. Of the two, free ammonia is the most toxic and increases proportionately to increasing pH.

Aquarium use only! Keep away from children.
