Healthy aquariums with conditions close to nature
The right water values are dependent on the fish stock and the plants in the aquarium. Even if the water looks clear it can be contaminated. With bad values diseases or algae can appear in the aquarium. To maintain a healthy aquarium with conditions close to nature it is important to check and adapt the water values regularly. With the JBL Testlab ProScape you can determine the 9 most important water values in your plant aquarium.

Precise measurement of the following values:
pH test: acidity of the water from 6.0 to 7.6
CO2 Direct: immediate determination of main plant nutrient carbon dioxide (CO2)
KH test: pH stability of the water (carbonate hardness)
Fe test: iron value to control the fertilisation
NO3 test: monitors the plant nutrient nitrate (another possible reason for algae growth)
PO4 test sensitive: determines the phosphate content (another possible reason for algae growth)
SiO2 test: cause of diatoms
Mg test: plant nutrient magnesium
K test: plant nutrient potassium

You can analyse the water values you have measured in the JBL Online Laboratory free of charge and receive recommendations, or have the precise consumption of individual substances in your aquarium individually calculated with the JBL Dosage Calculator. No more following instructions and dosing approximately, in future you can follow the consumption of your aquarium plants and dose precisely!

Where can I find the record sheets for the documentation of my water analysis?

Have you lost your record sheets, already filled them all in or do you need them in another language?
With the following links you can quickly and easily print out your new record sheets with recommendations for the individual parameters at home and document the water analyses.

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.

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

Why are there no colour charts for GH. KH, Mg /Ca saltwater and CO2 direct?

The tests from the test range: JBL GH test, JBL KH test, JBL calcium test Ca and JBL magnesium test Mg, where the number of drops are counted until the colour changes and the counted value is multiplied by a value:

GH = number of drops = general hardness in °dH

KH = number of drops = carbonate hardness in °dH

CO2 = number of drops * 2 = CO2 in mg/l

Magnesium + calcium = number of drops * 120 = amount Ca + Mg in mg/l

Calcium = number of drops * 20 = amount Ca in mg/l

Magnesium = amount Ca+Mg from magnesium test - amount Ca in mg/l = magnesium in mg/l

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.

Therefore, if the comparator block is not used, there will most likely be deviations in the readings.

Which scale applies for my aquarium? My test has two or three control fields with fish and recommendations.

We repeatedly receive questions regarding the symbols on the water test. The hobby areas cannot be clearly assigned to the scales for analysis. There are three symbols to make the hobby areas on the colour charts clear:

Discus = fresh water
Emperor = salt water
Koi = garden pond

In the following, you will find a list which assigns the scale for analysing the results from measurements in the hobby area and explains the symbols: The scales are described from the top to the bottom here.

NO3: salt water, fresh water, garden pond
pH 6.0 – 7.6: fresh water, garden ponds
pH 7.4 – 9.0: salt water, fresh water, garden pond
Fe: fresh water, garden pond

The following JBL tests have a uniform scale for all 2 or 3 hobby areas for analysis of the results from the measurements, as differentiation is no longer necessary:

SiO2
Cu
NH4
NO2
PO4
pH 3-10
O2

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).

Here’s how to do it: dilute the sample with distilled water and carry out the test once more.

This works in detail as follows:
GH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.
KH test: Instead of 5 ml use 10 ml aquarium water. Now 1 drop is equivalent to 0.5 dGH.

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.

NH4/NH3 ammonium/ammonia, NO2 nitrite, Fe iron and Cu copper:
2.5 ml sample + 2.5 ml dist. water: result times 2
1 ml sample + 4 ml dist. water: result times 5
0.5 ml sample + 4.5 ml dist. water: result times 10

NO3 nitrate, SiO2 silicate, PO4 phosphate sensitive and Mg magnesium freshwater:
5 ml sample + 5 ml dist. water: result x 2
2 ml sample + 8 ml dist. water: result x 5
1 ml sample + 9 ml dist. water: result x 10

PO4 phosphate koi high range:
2.5 ml sample + 2.5 ml dist. water: result x 2
1 ml sample + 4 ml dist. water: result x 5

K potassium:
7.5 ml sample + 7.5 ml dist. water: result x 2
3 ml sample + 12 ml dist. water: result x 5
1.5 ml sample + 13.5 ml dist. water: result x 10

K potassium in marine water:
1. Fill 10 ml of sample water with distilled water to 300 ml.
2. Follow the instructions for fresh water.
3. Multiply the test result by a factor of 30.

CO2 direct, Ca calcium and Mg+Ca magnesium+calcium: not required.

Do my water tests still work although they have been open for nine months?

Basically a sealed test keeps longer than an open one. How much the shelf life is reduced depends crucially on the handling and the storage conditions of the reagents. It may happen that a reagent in a test that has been open for 9 months doesn’t indicate correctly any more. However, additional information is needed to answer this question properly.

Getting rid of diatoms - no problem at all

If a brown coating covers the substrate of your aquarium and looks unattractive, let’s hope it is diatoms! The alternative would be smear algae - and they are not as easy to get rid of as diatoms.
