Dripping Kalkwasser...Help.

[fishcraze]

I do the calibration when I get a new probe. They are usually stable for about 1 year so I try to calibrate them once a year (if I remember. They normally reach end of life around 2 yrs, that when I'd start seeing erratic readings from the probes.

Every time I used it. Even then, I cannot trust it. I just file it away in the round filing cabinet and just forget about pH of my tank. I even not check the pH of my Calcium reactor. I just do bubble count and go from there.
pH of the tank is not really important any way. I never adjust it. There is not away to adjust it. If I added kalk too fast I can see that the coral is irritated a little. Fish never show any sign of problem with having tank pH spike up due to kalk addition.

I think otherwise. Frequent pH instability/fluctuation can affect your fish (ich!) /clam and coral health.
