I have a box of test strips and the box shows the following colors.
From top to bottom it shows Nitrate pink, Nitrite beige, Hardness green, Alkalinity yellow, and pH orange. When I test, the strip shows the Nitrate and Nitrite are fine, the Hardness is orange not green, Alkalinity is blue not yellow and the pH is dark pink or rose not orange. What is wrong? I just got the tank and set up and don't want to buy fish until everything is as it should be.
