For anyone who is familiar with red sea alk pro test kits, I am reading the directions and it says to fill the vile to 10 ml with water to be tested. did that. next it says to draw exactly 1.0 ml of alk pro titrant. did that. then it says to carefully add titrant to vile of test water until it turns to end color. the problemm is it starts light blue then it never goes to purple, instead it turns yellow which happens to be the color of the titrant. help!
