Ammonia from the gills of fish, their urine, and rotting food or decaying plant matter are contributors of ammonia in an aquarium. It exists in two forms in the aquarium and the first step is to understand the difference between ammonium NH4 and free ammonia NH3. NH3 (ammonia) is a gas and sometimes called toxic or free ammonia.

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 see NH3 levels. New Salicylate based tests, with two sets of reagents measure NH3. If your ammonia test kit registers in shades of yellow to green to blue, its salicylate.

NH3 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. The seneye.me website ...

The NH3 then reacts with the chemistry in the test to create the colour change that is measurable by the photometer or eye. The value that is outputted is either TAN or NH3-N. This method of testing means that the NH3 level that is being measured is …

We know high levels of NH3 (ammonia) is harmful to fish in the aquarium or pond but reducing them can often be a problem. Please follow this link to understand what are safe NH3 levels. All aquariums should have a biological and or chemical filtration to control ammonia.

NH3 cannot be calibrated as all calibration fluids would be very unstable when stored due to off-gassing. With a seneye device you should not need to use calibration as the replacement seneye+ slide does this.

Using traditional methods free ammonia is very hard to measure so normally people measure non-toxic ammonium 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 / NH4 at a given pH and temperature it is better ...

They may not register ammonia as the filters are keeping up with its production, however sometime bacteria colonies can be affected and population’s crash, this can be caused by water parameter fluctuations or pollutants; when this happens the same rules apply here as to removing ammonia as a it does to new aquariums and ponds. On ponds ...

Free ammonia NH3 can go up when you do water changes if the new water has has a higher pH. NH3 and NH4 always form equilibrium with pH and temperature. When you do a water change the new water will often be harder and have a higher pH than the water you are removing.

If NH3 levels rise to unsafeduring cycling, a number of measures can be deployed to lower pollution levels. 1ppm of ammonia or ammonium (ammonia) will make 2.7ppm of nitrite which will make 3.6ppm of nitrate. Please note however that NH3 …
