Calculate Gallons for Alarm (typically 2-3 inches) <br /> Alarm Depth(inch)x Gallons Per Inch (Line 2) <br /> x 25.0 = 75 Gallons <br /> 20. Calculate Total Gallons =Gallons Over Pump (Line 5)+Total Dosing Volume (Line 12)+Gallons for Alarm (Line 19) <br /> 250 + 218.0 + 75 = 543 Gallons <br /> 21.
