Sera Nitrate No3 Test Kit

Sera Nitrate No3 Test Kit

Sera Nitrate No3 Test Kit is a water test kit for monitoring the nitrate level in both freshwater and marine aquariums. Because nitrate (NO3) is an indicator of severe organic pollution, regular checks give South African fishkeepers and reef hobbyists an early warning that tank conditions need attention. It suits home aquarists, planted-tank keepers and saltwater enthusiasts who want a straightforward way to keep track of water quality.

Key Benefits

• Makes it easy to monitor the nitrate level in fresh and marine water, so one kit covers both types of aquarium.
• Tracks nitrate (NO3), a key indicator of severe organic pollution in the tank.
• Helps you spot a build-up early so you can find and remove the source of the organic pollution.
• Indicates when a partial water change is needed, which provides immediate help when nitrate is elevated.
• Sufficient for approx. 60 measurements, supporting regular, routine water testing.
• From Sera, a long-established name in aquarium water care and testing.

Suitable For

• Freshwater aquariums, including community and planted tanks
• Marine aquariums and reef systems
• Aquarists who want to keep a close eye on organic pollution as part of their regular maintenance routine

Compatibility

When a test shows nitrate is high, the source of the organic pollution should be eliminated and a partial water change carried out for immediate relief. For longer-term control, Sera recommends filtering through sera siporax Professional, which helps avoid nitrate enrichment over time. Using this test kit alongside sera siporax Professional lets you confirm that your filtration is keeping nitrate in check.
