Sera Nh3 and Nh4 Test Kit Ammonium Ammonia
Sera Nh3 and Nh4 Test Kit Ammonium Ammonia monitors ammonium and ammonia levels in both freshwater and marine aquariums to help keep your fish safe. It suits South African fishkeepers who want a straightforward way to keep track of the waste-derived compounds that can turn harmful to their livestock.
Key Benefits
- Makes it easy to check the ammonium/ammonia level in fresh and marine water.
- Measures the total concentration of ammonium (NH4) and ammonia (NH3) together in a single test.
- Comes with a chart that lets you work out the actual toxic ammonia level from your water's pH value.
- Gives you approximately 60 measurements for regular monitoring.
- Made by Sera, a well-known name in aquarium water testing.
Why Ammonium and Ammonia Matter
Ammonium and ammonia come mainly from fish waste. They convert into one another depending on the pH of your water. Ammonium is mostly harmless, but ammonia is toxic to fish. Because the balance between the two shifts with pH, knowing only the combined total doesn't tell you how much of it is the dangerous form. That is why this Sera test pairs the total NH4/NH3 reading with a pH-based chart.
How to Use
Use the kit to measure the total ammonium/ammonia concentration in a sample of your aquarium or marine tank water. Then look up your water's pH value on the included chart to calculate the actual ammonia level. You will need a current pH reading for your tank to use the chart.
Suitable For
- Freshwater aquariums
- Marine (saltwater) aquariums
- Fishkeepers who want to check that waste-related ammonia isn't building up to unsafe levels

Frequently Asked Questions
Can I use this Sera ammonia test kit in a saltwater tank?
Yes. It is designed to monitor ammonium and ammonia levels in both fresh and marine water.
What is the difference between ammonium and ammonia?
Both mainly come from fish waste and convert into one another depending on pH. Ammonium (NH4) is mostly harmless, while ammonia (NH3) is toxic to fish.
Does the test show the toxic ammonia level directly?
The test measures the total concentration of ammonium and ammonia combined. You then use the included chart with your water's pH value to calculate the actual ammonia level.
Why do I need to know my pH to read the results properly?
The ratio of harmless ammonium to toxic ammonia changes with pH. The chart uses your pH reading to show how much of the total is ammonia.
How many tests does one kit give me?
The kit is sufficient for approx. 60 measurements.
