Can I use the same Dos for dosing and water changes? I am setting up two Dos's on my tank. I plan to use one to dose Alk and Calc and the other to dose Magnesium. I would also like to use the other one to do water changes. Could I set up virtual outlets and toggle between the two when I want to do a water change? I would mainly use it for doing the Magnesium but then would switch over to do a 5 gallon water change within a short amount of time and then switch back to dosing.
