I have an Eheim 2080 on a 54 gallon corner aquarium. The filter has too much flow, so I set it to about 3/4 flow. My issue is that the 2080 theoretically should be way oversized for the tank and there's still a bunch of stuff floating in the water. For the first few months the water was clear, but more recently it doesn't seem like the filter is working great. It still has tons of flow and I just cleaned it the other day to be sure. I just have the blue prefilter pad, all three trays filled with biomedia, and the fine filter pad and a 50 micron pad I cut to fit. Do you think there's something wrong with the filter? Do you think the flow is just too much and is just rolling the stuff off the front glass, so it never makes it to the filter intakes? I've been wondering about replacing the biomedia in the bottom tray with some kind of mechanical media, but I'd think the fine filter pad would be stopping anything from going through the filter. I also considered making a custom spraybar that spread the flow out and lessened it. What do you think? Thanks.
