USER MANUAL NH4 Test JBL

Special features: The JBL ammonium test set is for the measurement and routine control of the am- monium/ammonia content in freshwater and saltwater as well as in garden ponds (koi ponds) within a range of 0.1 to 5.0 mg/l (ppm). Using the compensation method specially developed by JBL, precise and reliable results can be obtained even in moderately discoloured water, e.g. as a result of peat lters and disease treatment. Why test? The following applies to freshwater and saltwater as well as to garden ponds (koi ponds): The process involved in the breakdown or the mineralization of organic matter in the aquarium and pond (feed and plant debris, sh excrement) follows the following stages: proteins - ammonium - nitrite - nitrate. Certain bacteria are responsible for this process. Measuring the intermediate stages ammonium, nitrite and nitrate al- lows 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 concentrations of above 0.2 mg/l (ppm). If they do, the bacterial balance may be disturbed. Many of the medications used to treat sh diseases can damage benecial cleansing bacteria, leading to an increase in ammonium levels. As a rule, ammonium is not found in measurable amounts in a well-maintained aquarium with an efcient biological lter or in a correctly planted garden pond. Ammonium is an important plant nutrient and is normally non-toxic to sh. But, depending on the pH value, the ammonium ion (NH

) may convert into ammonia (NH

) which is toxic to sh. This is why any ammonia measurement should always be accompanied by pH measurements. The following table shows the toxicity as factor of the pH value (at 25°C): May be harmful to sensitive sh and small fry. May be harmful to adult sh, very harmful to young fry. Very harmful to adult sh, lethal for small fry. Absolutely lethal for all species of sh.UK Remedy: Short-term measure (aquarium only) : Change about 50 % of the water. Do not allow the pH level of the freshwater to exceed the pH level of the aquarium. Long-term measure: Aquarium: Add cleansing bacteria with JBL Denitrol and JBL FilterStart. Use a suitable biological lter. Reduce feed, reduce density of sh stock, if necessary. Garden pond: Add cleansing bacteria with JBL BactoPond and JBL FilterStart Pond. If not already in use, install an efcient pond lter. If necessary, review general design concept of pond: is there sufcient ground-covering material, marshy area, working as a plant based purication system etc…? Instructions:

1. Repeatedly rinse both test jars with the water to be tested.

2. Use the enclosed syringe to ll each of the test jars with 5 ml of sample water.

3. Add the reagents to one of the test jars in the following sequence:

a) 4 drops of reagent 1, mix well! b) 4 drops of reagent 2, mix c) 5 drops of reagent 3, mix. Allow to settle for 15 minutes.

4. Place both test jars into the comparator block: the jar with added reagent into

the smooth end of the comparator block, the jar with untreated test water (blank sample) into the notched end of the comparator block.

5. Move the comparator block together with the jars backwards and forwards on the

colour chart, with the notched side of the block facing the scale, until the colour of the sample treated with reagent matches the colour under the blank sample as closely as possible.

6. Read the ammonium content in the notch of the comparator block.

Note: In the event that the colour of your test sample is darker than the colours of the chart, dilute the sample with distilled or ammonium-free water and measure again. Depending on the dilution, the result must be multiplied as follows to determine the actual ammonium content:

2.5 ml sample + 2.5ml dist. water: result x 2

1 ml sample + 4 ml dist. water: result x 5

0.5 ml sample + 4.5ml dist. water: result x 10
