How much chemical do I dose?

This is a question we are frequently asked when dosing chemicals in parts per million (ppm).

In an attempt to help our readers we have provided the following.  Calculation assumes SG is 1:1

100ppm = 100mg/L = 0.1L/m3

500ppm = 500mg/L = 0.5L/m3

1000ppm = 1000mg/L = 1L/m3
