Fluval Master Test Kit (Wide pH, Ammonia, Nitrite, Nitrate)
Fluval Master Test Kit (Wide pH, Ammonia, Nitrite, Nitrate)
Track the four water parameters that matter most.
The Fluval Master Test Kit checks wide-range pH, ammonia, nitrite and nitrate from one kit, giving a quick read on the core parameters that keep fish and plants healthy. It suits freshwater and saltwater aquariums, and also works on tap or source water before a water change.
Key features
- Tests wide-range pH, ammonia, nitrite and nitrate in one kit
- Suits freshwater and saltwater aquariums
- Liquid reagent drop tests, read against the chart in the included instructions
- Glass test tubes and a pipette included for repeat use
Specifications
| Spec | Detail |
|---|---|
| Parameters tested | pH (wide range), ammonia (NH3), nitrite (NO2), nitrate (NO3) |
| Water type | Freshwater and saltwater |
| Test method | Liquid reagent, colour-match reading |
Target ranges by setup
Ammonia and nitrite should read zero in a fully cycled, established aquarium. Nitrate is best kept as low as practical, with reef systems generally needing lower levels than freshwater tanks. pH targets vary by setup:
| Setup | Target pH |
|---|---|
| Freshwater community | 6.5–7.5 |
| African cichlid | 7.8–8.6 |
| Marine / reef | 8.1–8.4 |
What's included
- pH reagent (10 ml)
- Ammonia reagents – two 15 ml bottles and one 10 ml bottle
- Nitrite/nitrate reagents – one 17 ml bottle and one 10 ml bottle
- Nitrate reagent (10.5 ml)
- Pipette and two glass test tubes
- Instruction booklets
Suitable for / not suitable for
- Freshwater and saltwater aquarium keepers checking core water chemistry
- Checking source (tap) water before a water change
- Not a test for general hardness (GH) or carbonate hardness (KH) – these need a separate kit
- Not a test for other parameters such as phosphate or copper
Care and maintenance
Store reagent bottles upright and capped, away from direct sunlight and out of reach of children. Rinse test tubes and the pipette after each use.

Common questions
What does this kit test?
Wide-range pH, ammonia, nitrite and nitrate – the four parameters most likely to affect fish health day to day.
Does it work for saltwater tanks?
Yes, the reagents suit both freshwater and saltwater aquariums.
How often should I test?
Weekly suits an established tank, with more frequent testing while a new aquarium is cycling or after adding livestock.
What do I do if ammonia or nitrite reads positive?
A positive reading usually calls for a partial water change and a suitable water conditioner, then re-testing.
Does the kit include GH or KH tests?
No. It covers pH, ammonia, nitrite and nitrate only; hardness needs a separate test.
Can I use it on tap water?
Yes, testing source water before a water change helps catch pollutants before they reach the tank.
