I found that increasing the CO2 did not get rid of BBA at all unless it was just a few tufts of it. I have had to remove the infested leaves, clean the hardscape in bleach solution, and even dip some whole plants in bleach solution. But, the BBA only seems to return if the CO2 ppm drops for some reason. I certainly don't dispute that it is a good balance of all of the nutrients that is critical. |
