Effect of ionic strength on PH tests. In highly buffered (high KH) water, or a pH calibration solution different test methods will generally agree within a small tolerance. This is fine as most PH test systems are designed for lab use where solutions are highly buffered. However buffer strength can affect the results from different pH ...
The calculations and look up tables do not take into account ionic strength or air pressure which can both influence the NH3 / NH4 balance. A seneye device will measure deadly NH3 directly, if you have a seneye reef device you will also get an NH4 widget on your seneye.me dashboard. To provide this we do a calculation derived from the known pH ...
In the following passage we will try to explain how pH and KH are linked. As mentioned earlier the pH measurement is a ratio, how easy it is to change this ratio (pH stability) is dictated by the ionic (buffer) strength also known as KH. The images below illustrate how different ionic strengths can report the same pH value.
NH4 (ammonium) is a nontoxic salt. It is the ionised form of ammonia. NH3 and NH4 together are often referred to as total ammonia nitrogen (TAN). Under normal conditions, NH3 (ammonia) and NH4 (ammonium) will both be present in aquarium water. The two exist at an equilibrium point that is governed largely by pH and temperature.
If you would like to adjust the pH gradually, or if the water to be adjusted is soft or not well buffered, it is important to use an Acidic and an Alkaline buffer together to increase the water's KH and prevent dramatic pH swings in the future. For instance, Seachem recommend the ratios in the table below between their Acidic Buffer and ...

Using with a PC - online. Connect your seneye directly to the PC. If your computer or laptop isn’t close enough you can extend the cable length by 2.5m using the seneye USB extension.
The warning LEDs on the seneye device and the alerts you receive are controlled by the levels set on these widgets.
pH is a measurement that shows the ratio of +/- hydrogen ions in concentration and is commonly used in the analysis of soil a ...
