I went to balance my alkalinity and pH today. When I first read the water, the alkalinity chemicals change from green to red through the process (reading was 30ppm) and the pH read yellow (6.8 or below). I added a product called phUp which was Potassium Carbonate. After this point when I go to use the alkalinity chemicals I noticed the green color at start isn't as saturated, and when it transitions to red it almost doesn't go red at all, more like a pale clear orange. The r-0014 pH reading stays yellow no matter how much chemicals I add.
This has happened to me once before when I used Soda Ash (Sodium Cabonate) to try to bring up the ph. The chemicals stop being able to read the water even though I am moving it. Any ideas what I did wrong?
