Water test for measuring ammonia NH3 and ammonium NH4 in fresh and marine water aquarium.
The measurement scale of ammonia goes from 0 to 10 mg/l. In aquarium and pond, high ammonium level (NH4) is most commonly caused by defective functioning of the filter, due to poor or insufficient water purifying bacterial activity. Ammonium (NH4) turns into ammonia (NH3) when the pH reaches above 7. Therefore it is really important to check the pH value in addition to the ammonium level (NH4. If ammonia level (NH3) exceeds 0.02 mg/l is very harmful for fish gills and poisonous for water, in the long term. In this case, it is recommended to replace 50% of water and reduce the ammonia level utilizing NITRIDAC which promotes bacterial activity in the filter.
How to use?
1. Shake the bottled reagents well before use.
2. Rinse the test tube several times with the water to be tested and then fill with water to the 5 ml mark. Dry the outside of the tube.
3. Add 5 drops of reagent 1, cap the test tube and gently shake to mix for 5 seconds.
4. Add 5 drops of reagent 2, cap and shake in the same way.
5. Add 5 drops of reagent 3, cap and shake in the same way. After 5 minutes the test solution turns colour. Match the colour of the solution with the colour chart. For accurate readings compare the colours from above, under natural daylight and avoid direct sunlight. Determine the level of free toxic ammonia (NH3) depending on ammonium (NH4) and pH value, according to the chart. Thoroughly clean and dry the test tube after use, securely seal all reagent bottles and store in a cool, dry place away from sunlight. Keep the product out of reach of children.
