SHARKBUF® pH buffer is used to provide alkalinity for all water-based systems and is compatible with freshwater, brines, and brine polymer systems. SHARKBUF® pH buffer will dissolve in water and raise the pH of an aqueous system to 10.3. At pH 10.3, no more SHARKBUF® pH buffer will dissolve. The remaining undissolved product will dissolve if the pH starts to fall and thereby act as a pH buffer. SHARKBUF® pH buffer can be safer to use than caustic soda.
