The correct amount of CO₂ and the correct pH value
JBL recommends a CO₂ content of between 15 and 30 mg/l in aquarium water. This range is
marked with “CO₂ correct “ in the table above. 20 – 25 mg/l have proved to be ideal. This level
is not harmful to fish and at the same time promotes luxuriant plant growth. The function
Auto pH uses the average value, namely 22.5 mg/l CO₂, to calculate the appropriate optimal
value.
In special cases, e.g. for aquascaping, CO₂ contents of up to 35 mg/l may be required.
· Always start by measuring the KH of your aquarium water.
· In the section “CO₂ correct“ look for the pH value which is correct for the KH and the
desired CO₂-value.
· Set this pH value as your optimal value (set point) on the device (see chapter 7.4).
Please ensure that you only set pH values which are not harmful to fish. For example if the
KH is high, do not set a pH value under 7.00. If you wish to set a pH value under 7.00, the KH
must be reduced accordingly.
Tip: If you activate the auto pH (see chapter 7.5), the device automatically takes over the
setting of an optimum pH value which is appropriate for the KH of your aquarium and
ensures luxuriant plant growth without endangering the fish. The corresponding values are
given as the auto pH curve in the table above.

Setting the CO₂ quantity
The amount of CO₂ which has to be added for the desired pH value depends on various
factors, such as water movement, consumption by plants etc. and has to be calculated
individually for each particular aquarium.
· Begin with about 15 bubbles per minute in the JBL PROFLORA Taifin M CO₂
Reactor per 100 l aquarium water (this corresponds to about 10 bubbles per minute
using a bubble counter).
· After one day check whether the entered set point has been attained in the
aquarium and the device switches off the CO₂ supply now and then.
· Should this not be the case, increase the CO₂ supply to about 20 – 25 bubbles in the
JBL PROFLORA Taifin M CO₂ Reactor (about 14 - 16 bubbles per minute in a bubble
counter). If necessary, increase the supply in further small stages until the device is
set so that CO₂ supply is switched off about 3 – 6 times per day.
Please also follow the instructions for use of the particular CO₂ unit used.
