bio filter
This is a situation where cartridge filers are real nice. You can get cartridges of varying porosity to filter out what you want. For instance, you could get a filter rated at 3 microns and everything 3 microns and larger will be filtered out (and eventually, smaller than 3 microns as the filter clogs).
Now, I presume you have a hang off the back kind of filter. The problem you are experiencing is probably due to the clogging of the filter media, and water is going around the media without being filtered. You’ll need to pull the media out and replace it. Either rinse the current media and re-use that, or use fresh media. Repeat as needed.
You may also have a problem in that the filter is not properly circulating the water throughout the tank. If this is the case, the filter may not be sized properly, or the clean water is falling too near the filter intake. The first is easy to resolve, get a properly sized filter. The second can be more problematic. You’ll need to devise a method for diverting the outflow to go further away from the outlet.
