    I read that fluctuating CO2 levels will cause algae problems.

    Does that mean from levels lower than 30 to levels above 30 or would it still cause algae problems at high levels, say fluctuating between 40 and 70?

    Thanks,
    Bill

    Re: CO2 up and down.

    I understand it to mean that the daytime CO2 ppm needs to remain about the same day after day, not gradually drop to less than half, only to be jacked up again after a week. Day-night changes are not the issue, as I understand it.

    So if I was trying to get my CO2 to run around 50ppm and while I'm adjusting it during the week it jumped back and forth between 40 and 70 ppm, that shouldn't provide any advantage for the algae?

    Assuming those readings are correct, yes, they should not cause algae issues.
    Main thing is providing stable high CO2 to the plants.
