plants can't take advantage of just light or just co2 or just nutrients. Unless all three factors increase together, It won't be able to use the extra stuff your giving it. Co2 and nutrients are the limiting factor of your plant's light consumption. This means when you have this inbalance the algae can use up all that extra stuff. Don't invest in just light or just co2. Light is the only thing that won't occur naturally in the tank so people try to add as much of it as they can but it's pointless if you don't balance all the factors so your plants acctually use the light. Lol that's what I know for fact. I don't acctually have any specific experience because I don't run high tech.
