Can you operate JBL ProFlora CO2 cylinders (disposable & reusable system) horizontally?
No, because this can lead to the destruction of your pressure reducer. To ensure safe operation, all storage cylinders should only be operated upright. Never operate them in a lying position or upside down.

What can I do when the measured value of a water test falls outside the scale?
If one of your measurements reaches the end of the colour chart scale you can multiply the scale by diluting later tests with distilled water (e.g. JBL Dest). _x000D_ _x000D_ Here’s how to do it: dilute the sample with distilled water and carry out the test once more. _x000D_ _x000D_ This works in detail as follows: _x000D_ GH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH. _x000D_ KH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH. _x000D_ _x000D_ Note: when using 10 ml sample water the colour development is weaker with the first drops than with 5 ml sample water. Put the measuring container on a white underlay for a better readability. _x000D_ _x000D_ NH4/NH3 ammonium/ammonia, NO2 nitrite, Fe iron and Cu copper: _x000D_ 2.5 ml sample + 2.5 ml dist. water: result times 2 _x000D_ 1 ml sample + 4 ml dist. water: result times 5 _x000D_ 0.5 ml sample + 4.5 ml dist. water: result times 10 _x000D_ _x000D_ NO3 nitrate, SiO2 silicate, PO4 phosphate sensitive and Mg magnesium freshwater: _x000D_ 5 ml sample + 5 ml dist. water: result x 2 _x000D_ 2 ml sample + 8 ml dist. water: result x 5 _x000D_ 1 ml sample + 9 ml dist. water: result x 10 _x000D_ _x000D_ PO4 phosphate koi high range: _x000D_ 2.5 ml sample + 2.5 ml dist. water: result x 2 _x000D_ 1 ml sample + 4 ml dist. water: result x 5 _x000D_ _x000D_ K potassium: _x000D_ 7.5 ml sample + 7.5 ml dist. water: result x 2 _x000D_ 3 ml sample + 12 ml dist. water: result x 5 _x000D_ 1.5 ml sample + 13.5 ml dist. water: result x 10 _x000D_ _x000D_ K potassium in marine water: _x000D_ 1. Fill 10 ml of sample water with distilled water to 300 ml. _x000D_ 2. Follow the instructions for fresh water. _x000D_ 3. Multiply the test result by a factor of 30._x000D_ _x000D_ CO2 direct, Ca calcium and Mg+Ca magnesium+calcium: not required._x000D_

The instructions point out that the comparator block should be used to compare the colours. Can this be done without the comparator block as well ? Or is there a factor from this comparison that is required for the measurement ?
The colour charts are intended to be used with the comparator block. In addition, when the comparator block is used with the blank water sample, this compensates the inherent water colour._x000D_ _x000D_ Therefore, if the comparator block is not used, there will most likely be deviations in the readings.

Do bio-filter balls for nitrate removal have to be replaced after a while?
No, it is not necessary to replace the JBL BioNitratEx filter balls for nitrate removal. The balls are broken down by the bacteria and the carbon source they contain is used for nitrate removal. After 6 months you’ll need to refill the missing quantity (1 ball per 2-3 l water). Please do not remove the remaining balls, as they serve to inoculate the newly added balls. Please note that the balls need to be embedded in a layer of fine filter fleece so that the smallest parts of the degradation do not get into the other filter material. In marine water, the additional use of activated carbon is recommended to avoid initial cloudiness.

I have lost my colour chart. Can I download the colour chart for the test?
The colour cards are not available for download on the JBL website. The absolutely accurate colour reproduction that is required can only be achieved using a printer which can be re-calibrated before each printout. Most privately used printers are not accurate enough for this. _x000D_ _x000D_ You will find the colour chart bundle as a spare part on the respective product page and in the spare parts shop under: https://www.jbl.de/en/products/detail/8732/jbl-proaquatest-assortiment-color-chart
