Is the Pinpoint pH meter a good instrument for minoring my freshwater pH, should I buy something more expensive? I saw it at aquadirect and it seems to be an easy to use and cheap pH meter, it doesn't have the control for the solenoid valve, but I have decided to do without it in my CO2 tank. Does anyone of you use it or can tell me something about it?
