So, here's something weird. One of the filters is now not turning on to full flow. Eheim pro4e have a flow regulator that you can turn up or down; when turned up all the way a orange indicator light turns on. I've always had both filters at full blast, but now, one of the filters only goes up to ~80% flow.
If I electronically decrease the flow and then increase it, I can get the display to indicate full flow, but then after a couple of minutes, it goes back down to 80%.
Edit: the filter that's running at lowered flow is the one with my co2 inline diffuser on its outflow. I'm guess there may be a blockage and the filter is automatically detecting the resistance and decreasing flow accordingly. I'll clean the lines here in a week or so and test this hypothesis.
There was only one catch and that was Catch-22.
