Gotcha, ya I looked some on ebay, havent committed to buying any yet, was hoping that you would have some 'in' with the hospital
Ya I am also planning to use only masterflex pumps on anything that is critical to the stability of the tank, like alk and calc
Still debating on going the dutch route, for a zero water change system, and that will require like 3-5 masterflex pumps for dosing
