I purchased the Knop S IV and am curious how to set it up. I also purchased American Marine Inc. pH controller. I see the pH probe hole on the top of the Knop S IV, I was under the impression you used the pH probe and controller to check the pH of the tank water and that adjusted the flow of co2 into the Knop reactor. But now I seem to be reading that you use pH controller to monitor the pH inside the Knop reactor or at least the effluent output, to keep it between 6.0 and 6.5. Is this correct? Also, does the larger media in the second small chamber on the S IV ever need replacing? If so, how do I replace it as I don't see a way to get it open as it appears glued together.
