    I just read an interesting article http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6T4F-4HTCW5J-1&_user=4607904&_rdoc=1&_fmt=&_orig=search&_sort=d&_docanchor=&view=c&_searchStrId=1142582265&_rerunOrigin=google&_acct=C000063561&_version=1&_urlVersion=0&_userid=4607904&md5=3fb04fc9b58f07d41111eb2f7596459e. The author used pH controlling system to keep CO2 supply at 170 μM, they found that the biomass of filamentous algae was higher than those kept at atmospheric equilibrium (17 μM CO2). Maybe stable CO2 along is not effective to control filamentous algae, but we still need high CO2 level.

    Where there plants in the test?

    If not.........does not mean much, adding CO2 increases algae growth some.
    pH controllers are not that accurate to maintain 170uM and 170uM is not nearly as much as we use.
    500-700uM ..........or 0.5 to about 0.7mM CO2
