Ph controller for CO2

[Ripley71]

I recently saw a PH controller on a C02 tank. How easy are these to set up/install on a tank? New to adding CO2.

Thanks

Pretty easy, so far I have one on each of my planted tanks. It will need to be calibrated once in a while (I do mine every month or try to). If you controller doesn't hold it's calibration then you will need to replace the probe (which runs about $20 -50). I try for a pH drop of 1, this should give your tank enough co2 to grow anything.
