As I mentioned at IMAC, I am exceptionally interested in these products, especially the model 3 calcium reactor. But I have lots of questions. What is the size and weight of the model 3? How does one attach it to the wall. It needs an input of what? CO2? Is a regulator required? Solenoid? How much time per day should it be on? How does water circulate? What pump is used on the reactor? Brand? How does one get water to the reactor from the sump? What pump? What line size? Anyone using this yet? Instructions? English? Cost for a model 3 reactor and all necessary equipment? (I have CO2 tanks and regulators but normal regulators seem to be obsolete) What else have I forgotten to ask?
