Waterlife Nitrate – 50 Tests
Nitrate is formed when nitrite is oxidised by nitrobacter filtration bacteria. Excessive nitrate levels in an aquarium can lead to poor fish colouration, lethargy, breeding failure, and increased algae growth. In seawater, high nitrate levels can cause stunted coral growth.
Ideal Parameters:
| Water Type | Tolerable Nitrate Level (ppm) |
|---|---|
| Seawater | 0 – 20 |
| Freshwater | 0 – 50 |

Stewart Springer –
Easy to use and gave clear results. I used it regularly in my freshwater tank and noticed a significant improvement in fish activity and less algae growth after a few weeks of testing and adjusting water parameters.
Boris Martin –
The test strips are reliable and the color change is easy to interpret. I found it helpful for monitoring nitrate levels in my marine tank, especially during water changes.
Emily Wallace –
Very accurate and consistent. I’ve used it for several months now and it helps me maintain stable nitrate levels in my aquarium, which has improved coral health.
