I bought the BRS CO2 scrubber and it made no difference in my ph. Will be taking it out of service. CO2 in room will equalize in tank with agitated surface of water no matter what. Best method to control CO2 is mentioned above, open windows and extend skimmer line outside. Make sure to carbon filter outside air esecially this time of year when neighbors start spraying weed killers etc.
