Atmospheric CO2 level
Hydrogencarbonate indicator is used to measure carbon dioxide levels in aquatic systems.
It is red in equilibrium with atmospheric air.
It becomes more orange/yellow with increased carbon dioxide levels.
It changes from red through magenta to deep purple as carbon dioxide is removed.
Green plants and algae use up carbon dioxide – removing it from the indicator as they carry out photosynthesis.
BUT.. they also produce carbon dioxide as they respire – all living things respire all the time
