Boron / Borate Buffering
Borate ions in seawater contribute meaningfully to alkalinity buffering and are consumed by some biological processes.
Unit: ppm Code: BORON
📖 Overview
Natural seawater contains about 4.5 ppm boron, primarily as borate. Borate contributes 10-15% of total alkalinity buffering in seawater. Depletion of borate is one reason mature reef tanks may show alkalinity drift despite adequate carbonate additions.
