Total Alkalinity is a measurement of three main ions: carbonate, bicarbonate, and borate. In saltwater, bicarbonate drives the pH toward 7.8, carbonate drives pH toward 9.1, and borate toward 9.5 or more. If you blend a buffer so that the combined product drives the pH toward 8.3, then the more you use, the more stable the pH becomes.

That is the principle behind Marine Buffer™. It is a blended buffer that drives and holds your pH at 8.3 because of the blend. The catch to this seemingly simple solution is that most salt mixes contain substantial amounts of bicarbonate salts. This shifts the ph of the buffering system further towards 7.8, and a buffer that shoots for 8.3 will never quite get there. Thus, the ph of Marine Buffer is actually slightly higher than 8.3 in order to combat the influx of bicarbonate at every water change. Marine Buffer™ was the first buffer on the market which contained borate salts (which make a saltwater buffering system much more stable), and Marine Buffer™ remains the most effective pH buffer on the market for marine aquariums.
