I built a 4”x24” reactor for dosing Kalkwasser but the 3000ml magnetic stirrer I purchased is just not very strong. It will stir a measured 3000ml of straight water but I don’t know if it will work when I add Kalk. Before I cut down the tube, does anyone have any suggestions for a reasonably priced magnetic stirrer that is strong enough to stir 6000ml? https://youtube.com/shorts/b6QHNvAXMNs?feature=share
