JBL Fe Test Set :Recommended level: 0.05 - 0.2 mg/l iron in freshwater
For approx. 50 measurements. For fresh- and saltwater.
Measurement range from 0.05 to 1-5 mg/l iron.
Responds to all dissolved iron compounds.
Colour scale with 9 colours from colourless to dark violet. Laboratory compensation system compensates water discoloration. Includes syringe to measure amount of water. Product description :The JBL Iron Test-Set Fe is designed for the measurement and routine control of the iron content in saltwater and freshwater within the range 0.05-1.5 mg/litre (ppm). The compensation method developed specially by JBL allows precise and reliable results to be obtained even in moderately discoloured aquarium water, e.g. caused by peat filters and disease treatment.
(Recommended level: 0.05 - 0.2 mg/l iron in freshwater) . Problem solutions : Iron :
Iron is one of the main nutrients of aquatic plants and should be available in the water of freshwater aquariums and garden ponds in concentrations of 0.05-0.2 mg/l. Too little iron stunts plant growth, too much iron results in algae problems. Measures to increase the iron content in the freshwater aquarium: The iron content can be increased by the addition of JBL Ferropol. Dosage can be monitored using the JBL Fe Test Set.
As an alternative to JBL Ferropol, JBL Ferrotabs can also be used to increase the iron content.
When setting up a new aquarium, JBL AquaBasis plus should be added to provide sufficient iron for the first few weeks. After 4-6 weeks the iron will have been used up and should be refilled using JBL Ferropol or Ferrotabs. Measures to increase the iron content in the garden pond:
The addition of JBL Ferolon increases the iron content of the pond water.
The dosage can be precisely monitored with the JBL Fe Test Set.
Measures to increase the iron content in the saltwater aquarium:
Small quantities of JBL Ferropol can be used to increase the iron content. Saltwater aquariums often react sensitively to excess iron in the water, resulting in increased algae growth. Why testing? Besides an adequate supply of CO2, aquatic vegetation needs iron and trace elements. Since healthy aquatic plants constantly consume iron and other trace elements, which only keep in the water for a limited period even when bonded to so-called chelating agents (usually found in modern fertilizers, e.g. in JBL Ferropol), the iron content must be monitored regularly with the JBL Iron Test Set Fe and replenish, if necassary. A concentration of 0.1-0.2 mg/litre (ppm) is normally adequate for good plant growth. A standard dose of JBL Ferropol corresponds to about 0.2 mg/litre (ppm). The JBL Iron Test Set Fe can also be used to measure the iron content in tapwater (normally iron-free) or in natural waters. Remedy: Iron content too low: fertilize with JBL Ferropol Iron content too high: change part of the water or filter with JBL Carbomec activ. Instructions : Repeatedly rinse both test jars with the aquarium water to be tested.
Use the enclosed syringe to fill each of the test jars with 5 ml of sample water.
Add 5 drops of Fe-reagent to one of the test jars and mix by agitating. Allow to settle for exactly 5 minutes.
Place both test jars into the comparator block: the jar with added reagent into the smooth end of the comparator block, the jar with the untreated test water (blank sample) into the notched end of the comparator block.
Move the comparator block together with the jars side to side over the colour chart until the colour of the sample with added reagent matches the colour of the blank sample.
Read the iron content in the notch of the comparator.
Please observe the safety notice on the reagent bottle! Our tip for the ecologically-minded aquarians: All reagents for the JBL Test Sets are also available in convenient and reasonably priced refill packs. The JBL test set series includes the following products: GH, KH, pH 4,5 - 9, pH 6,0 - 7,6, CO2, nitrate, nitrite, ammonium, phosphate, calcium.
Press Releas : Discussions on iron tests took up pages and pages on the Internet. There was a storm of complaints about the iron test of a competitor of JBL. For this reason, JBL?s Research and Development Department, led by Dr. Rainer Keppler, decided to look more closely at the subject of iron in aquarium water.
Iron in aquarium water really does not have it easy: on the one hand there is the oxygen which oxidises the iron up to unusable trivalent iron (Fe3+), whilst on the other hand there are the usual water conditioners which identify iron as a heavy metal and remove it, as is they are designed to do. JBL therefore protects its JBL Ferropol iron and mineral fertiliser with a chelate coating which protects the iron and the other minerals from exposure to the oxygen in the water and all other water conditioners. But that also means that the iron tests have a tough job, because the chelate coating protects the iron exceedingly well. JBL has therefore modified its iron test (Fe test set) such that all types of iron dissolved in the water are now detected, chelated or not! JBL is therefore the first manufacturer to offer a practical iron test with just a single reagent, which can even be used by the aquarium owner to test the fertilising quality. If the iron test immediately turns a lilac colour when adding an aquatic plant fertiliser, the fertiliser is of low quality whose iron and minerals are not protected by a chelate coating. If, on the other hand, the colour change takes some time and does not happen suddenly, we are dealing with chelated iron and minerals such as JBL Ferropol, for instance. To be able to determine the need for added fertiliser, an accurate grading of the colour scale in the lower range also makes good sense. The JBL colour scale shows values of 0.05 / 0.1 / 0.2 / 0.4 right through to 1.5. As the colour comparison is made with a laboratory-type comparator system, any natural colouring of the water is unlikely to falsify the results. The test is suitable both for freshwater and for saltwater.
