What is ammonia NH3 & NH4? - seneye
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 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 ...
NH4 and NH3 calculations & tables - seneye
NH4 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
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.
Is my seneye+ slide damaged - Seneye
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 chemicals may stain the sensor pads rather than harm the chemistry, and since a Seneye sensor calculates pH and NH3 values based on the colour of the sensor pads, this ...
seneye slide NH3/pH
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.
Photometer and reagent ammonia tests - seneye
Why? 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 or eye.
Fitting and registering your seneye slide
The seneye slide is for your NH3 and pH readings; without a valid slide fitted you will not receive SMS alerts. You will need to soak your slide in the water it will monitor before fitting it so that it stabilizes: 24 hours before for freshwater and 48 hours before for salt water. You can soak your slides in a container of the system water.
what is ammonium NH4 ? - Seneye
NH4 (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
pH 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.
Ammonia Test Kit - seneye
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 by AmQuel and similar products, but they do take longer to develop a reading and are more complicated to use correctly which can affect accuracy.
