    Hi

    I don't think "typical bubble rates" or drop checkers are good measurements of CO2 levels. What is a good bio-indicator? Something that's been proved. I read about Riccia stones, etc. but surely this is also linked to light levels? Then leads to the next question: how can you use a bio-indicator for CO2 if you don't have a standard reference for light levels?

    Regards
    Laure

    Hi Laure,


    Your plants are the best indicator you have. If you have poor growth, algae, melting, etc you most likely do not have enough c02 for your bio-mass.

    A drop checker is good to get an APPROXIMATION or GUESSTIMATE only, but they can be a useful tool, just don't rely on them :)

    Are the plants doing well? Is there pearling at all?

    Light levels drive growth and c02 and nutrient demand

    As long as you can MEET the demand for the lighting levels it is a non-issue.

    Most of us have way too much light and that causes issues as we don't keep sufficient and stable c02 levels.

    Hope this helps.
