I have a used lab grade digital peristaltic pump for sale. Works well. Good for dosing kalkwasser or just for auto topoff. Lowest speed is 11.4 gallons per day. I recommend putting it on a timer and running it just at night, for a fraction of the night. For example, if your evap rate were 1 gallon per day you would run it for 2 hours, spaced out, over the night. Can work with a timer, or float switch. Max flowrate is 640 gallons per day. I have a different pump head if you want to flow lower than 11.4 gallons per day. You can also mount extra heads if you want to dose other stuff, but all the heads must turn at the same RPM, but if they are different bore sizes they will flow different amounts. With a pair of low flow heads this could be used as a B-ionic dual part dosing pump.
I guarantee the pump for 30 days. However I have used these identical pumps in my lab, and they are good for a LONG time, I used 24/7. Occasionally (about once/year or so if continuous use) they need to have the brushes replaced. Easy to do, and parts not expensive.
