Hi everyone. Something I've been wondering about is the extent to which photorespiration might eventually become growth-limiting in high light/high CO2 tanks. If aquarium water becomes saturated with O2, or perhaps even supersaturated, is there any reason to believe those levels are high enough to partially inhibit CO2 utilization by aquatic plants?
I posted about this in another thread but it got closed before there was much feedback. Has this idea ever been hashed around?
