I run one and I get weeks out of it, but I don't run it 24/7, just at night. My skimmer isn't huge, just a HOB eshopps skimmer.
I removed the intake nozzle and only have the output nozzle connected, which allows for slightly more airflow. If I leave the scrubber attached to my skimmer during the day, my pH would be 8.6 or higher. Make sure you have a tight seal and the media is tightly packed.
Also, make sure your air intake to your skimmer isn't pinched or obstructed. Are you able to draw air from outside? If not, then it can only improve your o2 levels slightly.
