Another Doser question

[mrtian97]

I am currently dosing 200mL per day of each Ca and Alk using Jebao. Have too many mishap with this doser. I use Reefkeeper Lite to control my heater and my pH probe already not working.

Questions:

1. Is “stepper” motor (like DOS and GHL Maxi doser) more durable than the typical “peristaltic” pump?

2. I only need 2 heads pump since only dosing Ca and Alk

I like to have wifi ability. Any suggestions of the following:

A. DOS with also buying Apex EL
B. GHL Maxi doser
C. GHL 2.1 SA
D. kamoer C4

Thanks

200 ml a day? Please tell more about your system and all of your parameters please.
Yes, Steppers are far superior to other dosing pumps.

It’s a Redsea 350, parameter Alk 7, Ca 400, I have lots of sps and lpa colony, system setup for 2 yrs now. Growth has been great. I use kalk with my ATO, but plan to change to just dosing 2 parts
