Kamoer x1 Pro T or Neptune DOS for kalk dosing?

[B's Reef]

Im about ready to start dosing saturated kalk to my 65 gallon reef. Really only need a single head, trying to decide between these 2 dosing pumps. My plan is continuous dosing at a very slow rate throughout the day. May try only at night. We will see. But which would you pick and why?

Do you have an Apex controller?

Following. I’ll vote the DOS, just because you can program it with your apex. Though I can see why someone would suggest otherwise as to not put all your eggs into one point of failure. My personal plan is to use 2-DOS units. One head for kalkwasser through a reactor only at night. The other three for BRS tropic Marin 3 part DIY to pick up the back end of what kalkwasser cannot supply
