Thanks. I run 25+, that's why I'm asking. 20 is clearly enough for plant health. And with a venturi diffusing the CO2, with a controller turning the CO2 solenoid on/off, I can sustain ANY practical level... need 75 ppm? Can do, no problem.
The question is... how high does it need to be to be an effective algaecide?
