*Use a 80-120 alkalinity range for pools/spas using high pH sanitizers such as sodium hypochlorite [liquid bleach] or calcium hypochlorite. Use this range if Total Hardness is >300.

** A higher (100-150) alkalinity range is best for pools/spas using low pH sanitizers such as stabilized forms called dichlor or trichlor as well as bromine.
