Frequently Asked Questions

Q: What types of water can I test with this pH Test Drop Solution?

A: This pH test drop solution is suitable for a wide range of water sources, including freshwater aquariums, swimming pools, outdoor ornamental ponds, household drinking water tanks, and tap water. It is also great for school science experiments where quick pH readings are needed.

Q: How long does the 50ml bottle last?

A: Each test uses just 3 drops of solution per 50ml water sample. A standard 50ml dropper bottle contains approximately 1,000 drops, meaning you can perform hundreds of individual pH tests before needing a replacement. The solution remains valid for up to 2 years when stored correctly — sealed, away from direct light, in a cool location.

Q: Do I need any special equipment to use this water pH tester?

A: No special equipment or technical knowledge is required. Simply add 3 drops of the solution to 50ml of your water sample, shake gently, and compare the resulting colour to the included colour reference chart within 30 seconds. It is completely battery-free and requires no calibration.

Q: Why must I read the colour within 30 seconds?

A: The chemical reaction that produces the colour change is time-sensitive. After 30 seconds, the colour begins to shift and may no longer accurately reflect the true pH of the water sample. Always read and compare the colour against the chart promptly to ensure an accurate result.
