Systems and methods for monitoring and compensating for bleach concentration changes within a disinfection system may be provided. A bleach concentration monitor may be introduced into a disinfection system to measure the percentage concentration of a bleach precursor that may be introduced into a mixer and then report the measurements to pump controls within the disinfection system. Data relating measurements of the concentration of the bleach precursor may be transmitted to pump controls within the disinfection system so that adjustments may be made to a control algorithm within the pump controls to compensate for any changes that may be observed related to bleach concentration in the system.
