Who doses Kalk through a Kalk stirrer/reactor?

[reefinnewb]

My set up is simple. I feed my kalkstirrer with RODI using a dedicated peristaltic pump. The dosing rate of effluent is 4 ml per minute. This set up is completely independent of my auto top-up set up.

Did you DIY this? If so, which stepper motor board are you using? I have stepper motors and drivers from building a 3d printer. I don't feel like interfacing anything to an arduino, basically just want to plug it in to my apex to control timing and go.

No I did not. What you see in my photo is Deltec KM 500 kalkstirrer.
