Hello everyone. I currently have two DOS units and have 3 pumps dedicated for dosing Ca, KH, and Mg - all ESV products. I have not dedicated my last pump. I think I would prefer something that I don't have to shake or stir. Although I could at a small pump in my reservoir.
What options do I have?
Thanks,
Fast Eddy
