I did count the bubbles years ago when I first setup my CO2 system. Now I have Milwaukee PH controller and I would never setup a show tank without one. This very user friendly toy would put those LaMotte test kits to shame .

Aren't pH controllers a pain to maintain...with all that buffer, and probe changing?

Raul,

So far I have yet to have any problems. I never had one before so I basically went with what people told me. Buffering is fairly easy. Take probe, dip it in 4 and 7 solution and calibrate (screw on the back and front). This process takes few minutes. Some people have their probes for a long period of time and report no need for calibration.

Probe changing ?

Don't know about that.
