What's the best way to raise it? The true meaning of life is to plant trees, under whose shade you do not expect to sit. ~Nelson Henderson

As Bruce eluded to, pH has diel fluctuations. pH will be greatest in the late afternoon, and lowest in the early morning. The alkalinity is the measure of negative ions (buffering capacity) in the water, i.e., Bicarbonate and carbonate. The greater the alkalinity, say 20 ppm and greater, the more buffer you have in your water. The buffer keeps the pH from fluctuating from one extreme to another. One way people raise the pH, especially in the south is to add agricultural limestone, which is calcium carbonate. It increases the amount of negative ions, which increases your alkalinity, resulting in an increased pH.
