freshwater as well as in garden ponds within the range 1-240 mg/l (ppm). Using the compensation method
specially developed by JBL, precise and reliable results can be obtained even in moderately discoloured
aquarium water, e.g. as a result of peat filters and disease treatment.
Why test?
The following applies to freshwater and saltwater as well as to garden ponds:
The process involved in the breakdown or the mineralization of organic matter in the water (feed and plant
debris, fish excrement) follows these stages: proteins - ammonium - nitrite - nitrate.
Certain bacteria are responsible for this process. Measuring the intermediate stages ammonium, nitrite and
nitrate allows certain conclusions to be made about the "function" of the system "aquarium" or the system
"pond". Normally, ammonium and nitrite should not be allowed to enrich above concentrations of 0.2 mg/l (ppm).
If they do, the bacterial balance may be disturbed.
A continuous increase in the nitrate content, especially in the aquarium, accompanied by a low or undetectable
ammonium and nitrite content, is characteristic of a well-functioning bacteria balance but indicates at the same
time a insufficient balance in the aquarium (too many fish, not enough nitrate-consuming plants, too few water
changes).In garden ponds this often happens with highly populated koi ponds without ground-covering material
and marshy area, which works as a plant based purification system.
In heavily planted aquariums without fish or with only a few small fish the opposite may occur: Nitrate becomes
a deficiency and needs dosed additions for the plants to thrive and grow. This is especially the case with so-
called aquascaping, a specialized trend to create underwater landscapes in the aquatic field.
If phosphate is present in the water in addition to nitrate, levels of nitrate which are too high promote the growth
of unwanted algae. This is why the nitrate content of the water should be kept below 30 mg/l (ppm) in freshwater
and 20 mg/l (ppm) in saltwater. In garden ponds the nitrate level should not exceed 10 mg/l and ideally it
should not be measurable. In ponds which have not been correctly planned, nitrates from fertilisers used on the
surrounding area can often seep into the pond.
