9 Add-ons for CO2 fertilization systems
Level 1:
CO2 night cut-off valve:
In combination with a
Dennerle CO2 magnet valve
, a time switch can be used
to stop the CO2 supply during the night, as plants do not consume CO2 at night. This provides a way to save
valuable CO2.
Level 2:
Fully automatic:
The
Dennerle pH controller Evolution
measures the pH value in the aquarium on
an ongoing basis and regulates the addition of CO2 precisely and fully automatically via the
CO2 magnet
valve
.
10 Disposal
Electrical equipment must not be disposed
of along with the normal household waste.
