My personal experience with eclipse filters is that they are not worth it. I have an eclipse 12 but all of them are similar. There is a flaw in the design and that is that it drops water onto the filter media from above while the media sits horizontally in the tray. Essentially, you have a foot long filter instert and only the first 3 inches of it get used during normal operation. My reccomendation is to get a filter with a vertical standing insert like AquaClear, or use your canister, that would work too.
