Last month I bought two dosing pumps on E-bay. They were obviously built for medical use, meaning they are bullet proof. One is two channel, that I use for B-Ionic two part and the other is a single channel that I am using to add micro doses of Kent Essential elements. These are deluxe and I recommend them highly. They can be set to add just a few milliliters per hour. I had to do something different for the Kalkwasser I add at night, because these pumps deliver a constant drip 24 hours. I have cut my water exchanges back to once a month and all parameters are rock solid so far.
