As I understand it:
Low (stable) CO2 (0-2ppm) = No Algae
High (Stable) CO2 (30-60ppm) = No Algae
But! Fluxuating CO2 or CO2 in the 15PPM range = Algae farm.
Does that mean that if I took a successful Low light tank which has never had algae and has good plant mass, then injected a random 15ppm or so of CO2 and let that fluctuate without making any other changes (Especially to the light) that I would start to grow algae?
Then if I pushed that same tank to a stable 40PPM the algae would go away but plant growth would increase?
I ask because I'm unclear what part Light plays in this relationship. Like, does a low light tank limit Algae by Light? Or is it the CO2? Why the need for low light? Is the plant damaged if we drive growth hard enough that CO2 is able to bottom out completely slowing growth and giving algae a foothold?
Thank you,
