Carbon Dioxide (co2) Question

For the Eheim unit, I am using two pads (a blue one and a white one), this bunch of elbow looking things, and two bag fulls of rocks. Does that sound okay?
Also, by using this new filter and those two co2 units, should my co2 problem be finally controlled? It's still the same level as it was with only one unit working. Please Please Please HELP out. I've never had such a sad looking tank in my life.
