    Alkalinity Test using DPD kit

    I'm using a DPD Deluxe kit from Leslies and I haven't been able to get a reading for Alkalinity yet. Like the directions say, I put the drops in to turn it green. Then I need to put in other drops until it turns red. It turns bluish, then yellow, but never turns red. I put in about 80 drops a couple times and quit (A couple times). My chlorine is about 8 from shocking. But I waited 2 days and tried again, but the same thing. Help

    Blue to yellow is the same transition as green to red, but it occurs in the presence of high chlorine or other oxidizer.
