Great dosing pump! Review by Scott
Well built solid product that feels like its going to work and go the distance. I have had this running for over 6 months to dose CA and KH and it doses the right amount every time. My dosing pump is 15 feet away from the sump and it runs great from this distance. Took some time to get the chemicals going through the lines, but once they were primed i was good to go. Set it and forget it. Also, love the interface. Easy to calibrate the pumps and program the daily doses. There is an auto and manual programming mode based on how much customization and control you need. For most people the auto program will dial in what you need to dose. (Posted on 12/12/2012)

Best dosing pumps I have used Review by MRB
I have used a number of other dosing pumps and the quality of the pump heads on these pumps is the best I have seen. No problems priming these pumps either, unlike many of the two-roller designs out there. Be sure to measure the actual output of each pump when setting up dosing. I measured a range of 51 - 62 ml per minute between different pumps with tubing traveling the same path. (Posted on 9/28/2010)
