Since I added borates to 50 ppm, I have noticed that my pH continues to climb from 7.5 (where I like it) to 7.8 despite my attempts to correct it with HCl. Now, I know that 7.8 is okay but this is the high end of acceptable and leaves no safety margin. Because I keep such close eyes on my numbers, I have not seen it go higher than 7.8 because I always intervene with HCl. Yet, despite my efforts, it continues to creep up every time. Maybe I just don't understand this secondary buffer system of borates quite so clearly but I assumed that I would have more stability in pH fluctuation in my water with borates. Yet it seems that I am no better off now than I was before adding borates as I am still using the same amount of HCl that I was before and perhaps, even more so. I wonder, if I were to leave it alone, would the pH would continue to climb to 8.0 or above or if it will stay at 7.8? No aeration is being performed at this time. Straight up BBB all the way.
