What is pH? The new Broad Range pH Test is for testing water within the pH range of 6 – 9. This pH test now covers the pH range more likely observed in your aquarium and also offers improved precision with 0.5 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 aquarium, 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 aquarium.
