About this item
  • ใ€ MONITORS NITRITE LEVELS IN MARINE AQUARIUMSใ€‘: Nitrite is the intermediate product in the nitrification process. Nitrite originates as a waste product produced by nitrifying bacteria as a result of processing ammonia. It is commonly encountered in newly set up aquaria, where there has been a significant increase in the number of animals in the aquarium, or if the filter has been disrupted.
  • ใ€ EASY TO USEใ€‘: Add 5 ml of water to be tested into the test tube provided. The middle mark on the test tube indicates 5 ml. Add 5 drop of the nitrite reagent to the test tube, cap the test tube and then shake. Wait for 2 minutes for the colour to develop. Once the 2 minutes has elapsed, view the test tube from the side and compare to the colour chart to determine the amount of nitrite present in the water. N.B. Colour will continue to develop after 2 minutes. Therefore, read the nitrite test immediately after the two minutes has elapsed. Attempting to read this test significantly after this time period may result in falsely high readings.
  • ใ€ HOW TO FIX NITRITE ISSUES ใ€‘: A healthy, mature aquarium should have 0 mg/l nitrite at all times. Any positive nitrite reading likely indicates a problem with the aquarium and should be addressed. If any nitrite is detected in your aquarium, determine the cause for the elevated nitrite (e.g. changes in stocking density, overfeeding, filter maintenance etc). Monitor livestock for changes and ill-health and carry out partial water changes to dilute nitrite if necessary. Add Marine Live Filter Bacteria to help repopulate the filter with marine nitrifying bacteria and restart the biological filtration.
  • ใ€ ACCURATE LIQUID DROP TESTS ใ€‘: All NT Labs water testing kits are liquid drop tests from a dropper bottle to ensure the drops are the same size. This method of testing is significantly more precise compared to using dip strips. The use of liquid reagents guarantees accurate and dependable results for each parameter, simplifying the process of monitoring and maintaining ideal water conditions in your aquarium.
  • ใ€ SUITABLE FOR ALL AQUARISTS ใ€‘: The ease of use of NT Labs Test Kits means they are perfect for use by beginners and seasoned aquarists alike.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
