 Description 

Product: Sera Aqua-Test-Set includes: pH-GH-KH-NO2

Contains all the most important tests for both freshwater and sea:

  • PH value (100 measurements)
  • GH-Total Hardness
  • KH-carbonate hardness
  • NO2-Nitrite (75 measurements)

 
Instructions for use of PH:

Shake well before using the reagent!

  1. Rinse the tube several times with water to be tested and then fill it up to the sign of 5 ml. Dried, then, the tube externally.
  2. Add 4 drops of reagent.
  3. Close the tube with its cap and shake it slightly. Remove the cover.
  4. Compare the colors immediately, putting the tube on the chromatic scale, looking down from the light of day but not in the presence of sunlight.
  5. The value is determined by the color of the reagent compared with the chromatic scale.
  6. Clean: before and after each test is necessary to clean the tube thoroughly with tap water.




Instructions for use of GH:

Shake well before using the reagent!

  1. Rinse the tube several times with water to be tested and then fill it up to the sign of 5 ml. Dried, then, the tube externally.
  2. The reagent is added in drops. E 'need shake the tube after each drop added until the color changes from red to brown and the last straw to a dark green.
  3. The number of drops used is the total water hardness (° dGH), pe 5 drops = 5 ° dGH.
  4. Clean: before and after each test is necessary to clean the tube thoroughly with tap water.



Instructions for use of KH:

Shake well before using the reagent!

  1. Rinse the tube several times with water to be tested and then fill it up to the sign of 5 ml. Dried, then, the tube externally.
  2. The reagent is added in drops. After each drop must shake the tube continuing to add drops until the color of the test goes from blue to green and then yellow.
  3. The number of drops used is the carbonate hardness (° DHK), pe 5 drops = 5 ° DHK.
  4. Clean: before and after each test is necessary to clean the tube thoroughly with tap water.



Instructions for the use of NO2:

Shake well before using the reagents!

  1. Rinse the tube several times with water to be tested and then fill it up to the sign of 5 ml. Dried, then, the tube externally.
  2. Respectively, add 5 drops of reagent 1 and 2.
  3. Close the tube with its cap and shake it. Remove the cover.
  4. Compare the color after 3-5 minutes, putting the tube on the chromatic scale, looking down from the light of day but not in the presence of sunlight.
  5. Clean: before and after each test is necessary to clean the tube thoroughly with tap water.


The test reveals the following water quality:

  • NO2-N: 5.0 mg / l and NO2: 16.5 mg / l = lethal immediately change a substantial amount of water, adding the products as described above.
  • - NO2-N: 1.0 mg / l and NO2: 3.3 mg / l = very dangerous; made a partial water change adding the products as described above.
  • - NO2-N: 0.5 mg / l and NO2: 1.6 mg / l = harmful; made a partial change of water adding the products as described above
  • - NO2-N: 0.3 mg / l and NO2: 0.9 mg / l = not bad, look for the causes of the malfunction of the filter.
  • - NO2-N: <0.1 mg / l and NO2: <0.3 mg / l = good quality, no worry.
