    Algae

    Hey, For my science project, I need to see how much CO2 was used by my algae. I'm going to be growing them in bottles. To measure CO2 intake, could I keep the bottle capped and trap the CO2 with KOH (potassium hydroxide) as KHCO3 (potassium bicarbonate, a solid). And then use a wet cotton ball...

    Maintaining pH

    Hi, I'm growing this algae called coccolithophorid algae for a project. I'm trying to see how it grows in certain levels of pH. The range that I'm testing is from 6-10. How can I change the pH level without killing the algae and how can I maintain the certain pH level? Thanks.
