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. However, salinity and the ionic strength of the water also influence this equilibrium ...

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 / NH4 at a given pH and temperature it is better to measure NH4 as an indicator of NH3 ...
The NH3 is the most likely to be damaged and it will turn grey and give false high readings. If you think you have damaged your slide through mishandling then simply fit a new slide. Q When I remove my device from the aquarium it shows a higher pH when dropped back in. Why? A.
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. Biological filtration uses bacteria colonies to convert ammonia to less harmful substances. Chemical filters remove the ...
