Hello! I've been using the API freshwater liquid master test kit on my tank to monitor the cycle, but I've been having a little bit trouble observing the pH value. I feel like the color is supposed to be one of the ones listed on the card, but I can't pin-point it. Hopefully someone can help me out??
