I'm getting back into the hobby with my first 200 gallon system and am getting into corals and their care. I have all Hydros controllers. I need a recommendation for dosing pump and control. I have a bag of Kalkwasser on it's way and am looking for the right way to dose it in my system. I was watching a youtube with Carlos and David about the 2ml dosing pump and quickly learned that wasn't the right solution (they said definitely don't use that dosing pump for Kalkwasser). So now I don't know what I should be using. Any suggestions?
