Mixing Charts for Rid O'Rust Dosage Use these mixing charts to determine how much Rid O'Rust Formula to mix with water in your feed tank.
As an alternative, the Online Dosage Calculator may be used to calculate Rid O'Rust dosage.
Important: The charts are based on (A) a 30 gallon feed tank, and (B) a 25 gallon per minute flow rate for the irrigation system. If your particular application has a different tank size or flow rate, the Rid O'Rust dosage figure must be adjusted. If you do not know your sprinkler system flow rate, you can approximate it by determining the number of sprinkler heads on your largest zone and multiplying by 3 ( Number of heads x an average of 3.0 gpm = Total gpm). Please note that Formula 500 is presented in quarts. All other Formulas are presented in gallons.
