I just shelved my last fluval filter (205) about two or three weeks ago because it began leaking at the seal and nothing I tried fixed the issue. Also, I hate the fact that tons of debris comes flying out of the fluval when I reconnect it, and I blame the patented ribbed-hose design. I found the hosing to be flimsy; cracks easily and doesn't wear as well as the green eheim hosing. I also don't like some of the design features on the fluval; like the hand operated primer lever, the auto-stop valve, and the hose elbow. I find some of these features to be more of a hinderance than a benefit, and they don't seem to stand up to the test of time like the simplier more straight-forward design of Eheims. Just my two cents.
