SALIFERT Nitrite Test kit for freshwater (NO2)

Description

Product:
Nitrites are the most common killers of aquarium fish so they are the compounds to guard against in the nitrogen cycle. Nitrites occur in the aquarium through the partial oxidation of ammonium ions. Nitrite-loving bacteria then convert the nitrite into nitrate (step 3), thereby rendering it mostly harmless.
The simplest first step in preventing nitrite build-up is to feed sparingly, making sure there are not too many animals in the tank.
Secondly, carry out partial water changes regularly (not exceeding 20% of the total volume) with well-aged water, not tap water.
Third, make sure there are not too many total living animals in the aquarium. Many who are new to the aquarium hobby forget that even though catfish, algae eaters, and snails are “cleaner fish,” each still produces waste and adds to the total nitrite.

Instructions:

Add 2ml of aquarium water into the test vial.
Add 1 level spoon of NO2 Powder and swirl gently for 30 seconds.
Allow it to stand for 3 minutes.
Place the test vial against the color chart to obtain reading.

For freshwater aquarium, a value of not higher than 0.1 mg/L is advised.

Note:
Keep out of the reach of children! Only for aquarium hobby use.
The use of protective gloves and eye protection is recommended.
Please read the instructions carefully before using the product.

The Salifert Freshwater Nitrite Test for Healthy Tanks

Nitrite is one of the most common killers in freshwater tanks because it appears mid-cycle and again whenever the biological filter is disrupted. This Salifert freshwater kit lets you confirm nitrite has fallen to zero before you trust a new tank with fish, and gives you a fast answer if stock suddenly looks gasping or lethargic. For Singapore hobbyists, it is also worth checking after a power cut stalls a filter or after heavy feeding.

Run the test in good light and read the colour against the chart for an accurate result. A nitrite spike usually traces back to overfeeding, overstocking, or beneficial bacteria not yet caught up, so the fix is feeding sparingly and giving the filter time. In warm 27-29C local tanks, cycles move quickly, but that also means a stalled filter can cause trouble fast.
