Electrochemical deposition systems and methods are described that have enhanced crystallization prevention features. The systems may include a bath vessel operable to hold an electrochemical deposition fluid having a metal salt dissolved in water. The systems may also include sensors including a thermometer and concentration sensor operable to measure characteristics of the electrochemical deposition fluid. The systems further include a computer configured to perform operations that include receiving system data from the electrochemical system and generating a control signal to change a characteristic of the electrochemical deposition fluid to prevent crystallization of a metal salt in the fluid. The computer generates the control signal based on processing that may include comparing an actual metal salt concentration in the electrochemical deposition fluid to a theoretical solubility limit for the metal salt in the fluid.
