These calculations are based on a known flow rate of water through the device and a known feed rate of dechlorination solution (a mixture of Vita‑D‑Chlor and water) into the device. This is useful for commercial devices like the deChlorinator and the H2O Neutralizer, as well as for homemade venturis. It can also be used with metering pumps.
When using the calculated results, it is important to remember that your feed solution of Vita‑D‑Chlor and water has limitations. Generally, no more than one pound of Vita‑D‑Chlor can be mixed into a gallon of water. This concentration can be increased to four pounds per gallon if you choose to use Vita‑D‑Chlor Neutral. The calculator equations are suitable for both Vita‑D‑Chlor and Vita‑D‑Chlor Neutral.

Formula
Pounds of Vita‑D‑Chlor per gallon of water = (Flow x PPM) / (750 x Feed)
Grams of Vita‑D‑Chlor per gallon of water = (3 x Flow x PPM) / (5 x Feed)
where
Flow=Flow rate of water through the device in gallons per minute (GPM)
PPM=Parts per million of Chlorine to be treated
Feed=Feed rate of dechlorination solution into the device in gallons per hour (GPH)
