What is ammonia NH3 & NH4? - seneye
WEBNH4 (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.
NH4 and NH3 calculations & tables - seneye
WEBNH4 and NH3 calculations & tables. Using traditional methods free ammonia (NH3) is very hard to measure so normally people measure non-toxic ammonium (NH4) in the aquarium and pond and use this as a guide to safe levels of NH3. In true terms NH4 is a nontoxic substance in the aquarium, however due to the equilibrium which occurs between NH3 ...
what ammonia level is safe - seneye
WEBNH3 is reported in the unit of ppm but this is interchangeable with mg/L as it is a gas dissolved in water. Want to reduce your ammonia because you have a high level or problem? If so then please click here. The seneye device and seneye connect application allows you to look at free ammonia between 0.001ppm and 0.500ppm.
what is ammonium NH4 ? - Seneye
WEBNH4 (ammonium) is a nontoxic salt, it is the ionised form of toxic ammonia NH3. It is useful to understand that in the aquatic environment NH4 is not toxic, however it does have the ability to instantly change to NH3 with a change in pH and or tempertaure. This is why people often worry about high levels of NH4 when they do water tests, as NH4 ...
pH and NH3 probe calibration - seneye
WEBpH and NH3 probe calibration. Normal systems for continuously measuring PH and other chemicals require calibration. Calibration should always be done using more than one point to ensure accuracy. Remember if you have a probe it will only be as good as the calibration fluids used to set it and these can greatly vary.
Photometer and reagent ammonia tests - seneye
WEBWhy? Many tests use the “indophenol method” for measuring the ammonia by drastically increasing the pH of the sample. The movement in pH means that all of the ammonium (NH4) in the sample will be liberated to the NH3 form. The NH3 then reacts with the chemistry in the test to create the colour change that is measurable by the photometer …
Ammonia Test Kit - seneye
WEBIf your ammonia test kit registers in shades of amber, it's Nessler. They generally are quicker to use, but ammonia-locking products (e.g., AmQuel) will cause Nessler kits to give false positive readings. Nessler test kits measure ammonia NH3 and ammonium NH4. This is important to note and often missed as you will need to use a look up chart so ...
reducing ammonia NH3 levels - seneye
WEBIf you see sudden spikes without a change in stocking or feeding levels than it is likely that either of these methods has failed, allowing ammonia to rise to unacceptable levels; a chemical additive or water changes is a good ways to reduce free ammonia levels. The root cause of high NH3 it can vary but usually it is worth checking the following:
seneye slide NH3/pH
WEBA. This is due to two reasons: the first is an adjustment of CO2 levels as it reaches an equilibrium with air not water (this happens fast). The second reason is as the slide starts to dry out (evaporation = only water), a change in the water chemistry will affect the pH. We would expect it to go back down a few hours after being introduced ...
Water chemistry - seneye
WEBGH – General Hardness. This is a measure of the calcium and magnesium in the water. PO4 – Phosphate, High levels will encourage algae growth. NH4 – ammonium, although not toxic itself a change in temperature or pH can release it into NH3. There are many more exotic chemicals that can be measured in the aquatic environment but most of ...
