Tunze 7074/2 - CO2/pH controller set

[Charley2015]

Hi, How many tanks can one CO2/pH controller manage? If I buy one 7074/2 set, can I use it to maintain a set pH of three or four tanks (all at the same pH)? Thanks for your advice

Unless all the tanks are interconnected and sharing the same water, it can only handle one tank as it would only have one pH electrode and one solenoid and no more can be added.
