The core micron filter seems like it is to long by about an inch to long. I can't put the lid on the media cartridge. This is for a magnum 350 bio pro system.
There are two different cores, one for the micron cartridge and one for the carbon media container. You should be using just the one longer one, without the other short piece. Also, you are talking about the core micron filter and then the media cartridge. You either run the filter with the core and micron cartridge or the core set and media container with filter sleeve. Not with both.
