Is there a formula somewhere that indicates what the increase in calcium is per amount of cal-hypo and increase in CYA per amount of trichlor
1lb of 73% cal-hypo for 21000 gallons of water = x calcium increase
1lb of trichlor for 21000 gallons of water = x CYA increase
1lb of 73% cal-hypo for 21000 gallons of water = x calcium increase
1lb of trichlor for 21000 gallons of water = x CYA increase
