NT Labs Narrow pH Test

For fish with specific pH requirements or for general tropical community aquaria requiring a neutral pH, the pH 6–7.6 Test provides quick and accurate pH measurement. It also offers precision with 0.2 unit determination.

What is the correct pH level?
There is no definitive correct pH as different fish species have their preferred pH range. Generally, the ideal pH value will lie between 7 and 8, but there are some exceptions. When purchasing fish from your local aquatic retailer, always enquire as to the specific water requirements of the fish you are buying.

What do I do if the level is wrong?
If you do need to adjust the pH of your pond, it is vital to do this slowly to not shock the fish. Change no more than 0.5 pH units per 2 days. Providing your tap water is of suitable pH, substantial water changes can correct a dangerous pH level. It is also important to check the KH of the pond. Use of pH adjusters, such as KH Buffer up will raise the pH caused by soft or aged water. For fish that live in soft, acid water use bogwood to gently lower the pH and soften the water.

How to use?

• Ensure the test tube is clean.
• Take a 5ml sample of water into the test tube.
• Add 5 drops of the pH reagent; replace the test tube cap and shake thoroughly.
• Compare the colour of your sample to the colour scale provided.
