Ac in tank
I just got a great instrument from Hanna Instruments. Its called the pH
turtle. It connects a PC computer running windows 3.1.1 or 95 etc to a
pH probe, and allows you to graph the output at various times into a log
Now the problem. My Fluval 403 and my Computherm heaters are inducing ~
0.01 ma apiece so I can't leave them on otherwise the meter goes crazy.
If I ground the tank water, apart from creating a potential problem for
the fish, I peg the probe at 14.0 pH.
So....What do you guys with the pH controllers do? Help George and any
other EE's out there.
Best to you
