Test NH3

Test NH_3/4 – for determination of ammonia concentration in aquarium water.

INSTRUCTION:

1. Rinse the test tube repeatedly with water to be tested.
2. Using the syringe, place exactly 5 ml of the water to be tested into the test tube.
3. Hold the bottle with Reagent №1 strictly vertical! Add 5 drops of reagent №1, close the vial with the cap and shake well for 10 seconds.
4. Hold the bottle with Reagent №2 strictly vertical! Add 5 drops of reagent №2, close the vial with the cap and shake well for 30 seconds.                                                                              5. Hold the bottle with Reagent №3 strictly vertical! Add 5 drops of reagent №3, close the vial with the cap and shake well for 30 seconds.
6. Wait for 15 minutes for the color in the reaction vial to stabilize at the endpoint. 
7. Match the color of the liquid in the test tube to the Ammonia Color Scale placing the test tube against the white area of the card. The closest match indicates the mg/l of total ammonia (NH3/4) concentration in the aquarium water sample. You should compare the colors in soft light! It is not allowed to compare them in direct sunlight or by lamplight, etc. 

ATTENTION!!!

The color in the reaction vial will remain stable for 5 minutes. Do not relate to the color in the reaction vial after this time. DO NOT compare the solution that stay for over 20 minutes after addition Reagent B, because color can change, and test will give more high levels of ammonia. After 20 minutes the color can change (depends on the temperature value) and test will give higher levels of ammonia.

Immediately after determination of ammonia level thoroughly wash test vial.

Avoid getting an indicator liquid or water after testing into an aquarium!

KEEP OUT OF REACH OF CHILDREN!

For accurate result temperature of water to be tested must be 25±3°С, and indoor temperature not less than 20°С.

Shelf life: 24 months, but not more than 12 months till open.
