Quick test to determine the pH values in freshwater aquariums in the range 6.0-7.6.

• Controls the water values in aquariums simply and reliably. Determines the ideal pH value for freshwater aquariums.
• Laboratory comparator system to compensate the inherent water colouring: fill plastic cuvette with sample water, add reagents to another cuvette, place both cuvettes in holder, read values on colour chart.
• When to use: for setting up a new aquarium: daily for one week, afterwards weekly.
• Online Laboratory: regular control for a healthy aquarium with conditions close to nature. JBL has water tests in the form of quick tests or colour change tests for every water analysis. Testing aquarium water for healthy, clear water.
• Package contents: 1 quick test, pH Test 6.0-7.6 for approx. 80 measurements. Incl. reagent, 2 glass vials with screw cap, syringe, dosing spoon, comparator bhttps://www.jbl.de/?lang=en&mod=products&func=detail&id=2433lock and colour scale. Refill reagent available separately.

pH Test Set 6.0 – 7.6 Special features: The JBL pH test set 6.0-7.6 can be used for the accurate measurement and routine control of the pH level in freshwater within the relevant range of 6.0 -7.6, and above all for the control and the optimum adjustment of CO2 -fertilization with the JBL PROFLORA CO2 system. Using the compensation method specially developed by JBL, precise and reliable results can be obtained even in moderately discoloured water, e.g. caused by peat filters and disease treatment. Why test? The well-being of fish and the growth of aquatic plants depend to a large extent on the pH level being kept as constant as possible. The pH level plays a significant controlling role in CO2 -fertilization. The CO2 -concentration best suited for plants and harmless to fish is reached with a pH level around 6.8 to 7.2, provided that the water does not contain any other substances which might influence the pH level. The carbonate hardness should not drop below 4° and not significantly exceed 18° dH. This means that a simple pH measurement is sufficient to check the best possible CO2 - fertilization. Precise measurements may also be required even if CO2 is not used for fertilizing, for instance for the breeding of special fish species. The pH test set 6.0 - 7.6 is also suitable in these cases. Remedy in case of pH fluctuations: To lower pH: CO2 fertilization with the JBL PROFLORA CO2 system or JBL pHMinus. UK To raise pH: normally not required in freshwater, otherwise with JBL Aquadur plus or JBL pH-Plus. Instructions: 1. Repeatedly rinse test jars with the water to be tested. 2. Use the enclosed syringe to fill each of the test jars with 5 ml of sample water. 3. Add 3 drops of 6.0 - 7.6 reagent to one of the test jars and mix by shaking. 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 the 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, until the colour of the sample treated with reagent matches the colour under the blank sample as closely as possible. 6. Read the pH level in the notch of the comparator. The instructions are repeated in a series of simple diagrams on the reverse of the colour chart. Our tip for environmentally-friendly users: All reagents for JBL test sets are available from your retailer as reasonably-priced refill packs!
