Product information

This permanent indication test uses colouration to show the aquarist the pH value and the CO2 content of the aquarium water at any time.
You can read off whether the pH value is within the optimal range and whether the plants have sufficient CO2 as their main nutrient available during the day 24/7.

How exactly does the test work?
The CO2 dissolved in the aquarium water diffuses in the container of the permanent test, passes into the air column containing the indicator liquid and then dissolves in the liquid. This creates a pH value, which results in the discolouration of the indicator liquid. The colour displayed corresponds to a certain pH-value and, depending on the carbonate hardness of the water, you can read off whether the resulting CO2 content is too high, too low, or optimal.
If another pH-lowering or increasing substance (e.g. pH-Minus) apart from CO2 is added to the aquarium water, it cannot diffuse through the air column in the permanent test and thus does NOT affect the indicator liquid. In this case the pH value displayed would not be correct. It only shows correct values, when there are NO other pH-influencing substances in the water besides CO2.

How long does it take until the test displays correctly?
Due to its design the test is somewhat sluggish, because the CO2 gas needs to first "migrate" through the air column in the test vessel, then into the indicator liquid and can only then be displayed. It can therefore take up to one hour until the test shows the current CO2 content of the aquarium water for the first time.

Recommended CO2 content:
Freshwater aquarium (community aquarium): 15-35 mg/l;
Lake Malawi-Tanganyika aquarium: 4-10 mg/l;
Plant aquarium with few fish (aquascaping): 20-35 mg/l

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

Have you lost your record sheets, used them all up, or need them in another language?
In the appendix of this FAQ you will find PDF files for printing them out in German, English and French.

Despite CO2 fertilisation the indicator remains blue

No CO2 is generated when fertilising with so-called liquid carbon. Therefore the test is not able to indicate CO2, which means that the indicator always remains blue! If you add CO2 in gas form you need to increase the amount or the duration.

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.

Is the fluid of the JBL CO2/pH Permanent Test harmful to the tank inhabitants if some of it gets into the water?

The fluid itself with the colour indicator is not harmful in any way with the high dilution in the tank and, in addition, it decomposes very quickly.

JBL CO2/pH Permanent: Does ozone affect or distort measurements in the CO2 permanent test?

Depending of the dosage it is quite possible that the ozone attacks the indicator of the CO2 permanent test and “oxidizes”. A reasonable continuous measurement of CO2 is then not possible with this method.
