NH3 (ammonia) is a gas and sometimes called toxic or free ammonia. This type of ammonia is the dangerous part. NH4 (ammonium) is a nontoxic salt. It is the ionised form of ammonia. NH3 …

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 …

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. …

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 …

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 …

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 …

On this slide the sensor pad for NH3 has started to change colour, so there must be some NH3 present, but the colour is not continuous across the entire pad. Stained Slides Some …

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. Salicylate test kits are unaffected …

The seneye device only measures toxic free ammonia NH3 and the seneye connect application allows you to look at free ammonia between 0.000ppm and 0.500ppm. The seneye.me …

Chlorine and Chloramine, even in very small amounts, will bleach the coloured sensor pads on the slide. Over the course of time, the pH / NH3 reading will normally decrease. Always ensure …
