Red Sea Nitrate/Nitrite NO3/NO2 Test Kit

Red Sea Nitrate/Nitrite NO3/NO2 Test Kit provides 50 Nitrate plus 50 Nitrite advanced colorimetric tests for marine aquariums

This combined test kit provides either 100 nitrite or 50 nitrate plus 50 nitrite advanced colorimetric tests for marine aquariums.

This kit is essential during the maturation of all marine and reef aquariums and is suitable for ongoing algae management with Red Sea’s NO3: PO4-X in fish-only systems.

Directions for Nitrite Test

1. Using the syringe provided, place exactly 5 ml of the water to be tested into the glass vial.

2. Add 3 drops of NO3/NO2 indicator close the vial with the cap and shake for 10 seconds.

3. Wait 5 minutes for the color in the vial to stabilize.

4. Remove the cap and move the vial between the designated positions on the Nitrite color card, look into the vial from above and compare the color in the vial to the colors on the card. Choose the Nitrite level that gives the closest color match and if necessary estimate an intermediate value.

5. The color in the reaction vial will remain stable for 1 minute. Do not relate to the color in the reaction vial after this time
