Temperature effect on pH readings
Temperature effect on pH readings
Hi, I was looking at the temperature and pH graphs and was wondering if there is some temperature effect on the pH readiongs. From the graphs it seems that there is some correlation

Re: Temperature effect on pH readings
The pH of a fluid will vary with temperature.
Take a solution that has a PH of 7 at 25 centigrade. At 10c it would be a PH of 7.27 and at 50c a PH of 6.63.
This is a reason why when setting up a PH probe the test solution packet will say what the correct temperature should be for the calibration fluid to be at to give that PH value.
Unless you are using the PH probe to adjust PH via a Calcium reactor I would not worry about it, as the readings are only an indication of the PH at a given time. Also PH varies through the day because of the effect of light on the tank.
So my guess is that what you are seeing on the screen is not a problem with the Reef Angel, but pure physics.
