This is a comprehensive water testing kit designed for people keeping fish in freshwater aquariums (and can also be useful in ponds). It’s often marketed with names like “6‑in‑1 Aquarium Water Test Kit – Up to 200 Combined Tests” because it lets you check six different water parameters with one kit.
What It Tests
The kit lets you measure six essential water quality factors that are key to fish and plant health:
Ammonia (NH₃‑N) – toxic to fish if levels rise
Nitrite (NO₂‑N) – also harmful at elevated levels
Nitrate (NO₃‑N) – less toxic but still important to manage
pH – acidity/alkalinity of the water
GH (General Hardness) – mineral hardness that affects fish health
KH (Carbonate Hardness) – buffering capacity that stabilizes pH
Up to 200 Combined Tests
The “200 tests” refers to the total number of individual parameter checks you can perform (not 200 of each test).
For example, if you test all six parameters each time, that uses six counts off the total.
How It Works
This is a liquid drop‑based kit — you add a measured amount of your aquarium water into a test tube, add a few drops of a reagent from the included bottles, and observe the resulting colour change.
You then compare the colour to the included chart to read the water parameter value.
The kit includes colour charts, labelled test tubes, an integrated rack, and colour‑coded stickers to keep things organised and avoid mix‑ups.
Why Hobbyists Like It
More accurate than simple test strips: Drop tests generally give more precise and reliable readings.
Covers the basics: It includes all the key freshwater parameters most aquarists need to monitor regularly.
Good for routine maintenance: Useful for checking water before water changes, after adding new fish, or when cycling a tank.
Tips for Use
Read instructions carefully: Good lighting and careful colour comparison help ensure accurate results.
Results are expressed in nitrogen terms: For ammonia, nitrite, and nitrate, results are reported as the nitrogen portion (NH₃‑N, NO₂‑N, NO₃‑N), which aligns with standard safe level recommendations in fishkeeping.
Store the kit in a cool, dry place and check expiry dates — reagent chemicals can degrade over time, affecting accuracy. (Anecdotally, liquid kits can still work past expiry but accuracy may vary.)

Understanding Nitrite
Nitrite is produced when beneficial bacteria convert toxic ammonia into nitrite as part of the aquarium's nitrogen cycle. A second group of beneficial bacteria then converts nitrite into the much less harmful nitrate.
While this is a normal biological process, any detectable nitrite is considered unsafe and should be addressed immediately.
What to Do if Nitrite Is Detected
0.25–0.5 mg/L (ppm): Add a filter booster such as Filter Starter.
1.0 mg/L (ppm): Perform a 25% water change.
Above 1.0 mg/L (ppm): Perform a 50% water change.
Check other important water parameters, particularly ammonia and pH.
Ensure your biological filter is functioning correctly.
How to Use
Ensure the test tube is clean.
Fill the test tube with 5ml of aquarium water.
Add 5 drops of the Nitrite reagent.
Replace the cap and shake thoroughly.
Wait 2 minutes.
Compare the sample colour with the supplied colour chart.
A colourless sample indicates 0 mg/L (ppm) nitrite. Any hint of pink indicates the presence of nitrite. Ignore any colour that develops after the initial 2-minute reading.
