I am thinking my pH chemical has gone bad...After adding my 5 drops, capping & shaking it up, the color is kind of orange. I have another old test kit that has been sitting outside for about a year & when I tried that one, I got a pretty low reading of about 6.8-7.0

I will be buying another small test kit today as well as having my water tested to make sure of my pH. I just wanted to get yall's opinions.
