Re: pH controller device

Actually, the "alarm" on the SMS 122 is not involved with the turning on or 
off of the power plug. There is a dial on the unit that is your setpoint 
adjuster. The alarm is simply a red led light that flashes on and off when 
the controller energizes the power plug. A visual indication that you are 
pumping CO2 into the tank. The dial on the unit is how you set the setpoint, 
which energizes the plug when the pH goes above whatever setpoint you have on 
the unit. My setpoint is about 6.8 like what you want.
