Well what the heck is going on here, I replied the same day, I know I did, guess I didn't press post, crazy... I'll try again. :)
Stepper motors are more accurate due to how they work. Instead of using time to determine how long it runs stepper motors use steps. Lets say the stepper motor has 200 steps per revolution and you wanted one revolution, you simply tell the stepper to turn 200 steps. With a regular DC motor you can't do that, you can only hope you get one perfect revolution. As the motor ages or if power supply gets weak maybe you only turn 98% of a revolution or 102%. Stepper motors are the main reason 3D printers function and can reproduce the exact same results, if a 3D printer had normal DC motors it would never work.
So yeah only for absolute precision is the stepper motor needed. If you wanted to dose 5 drops every time you would want stepper but for most aquarium dosing a standard dosing pump is fine. If you want to keep regular motor semi accurate it's probably good to recalibrate it every 3-6 months or verify it's still close.
