I've had my Eheim 2215 running with fish and plants in a 60 gallon tank for 3 months. About 2 weeks ago I took it apart to to rinse the media (in old tank water) and it has not run well since. Last week I took it apart again and rinsed everything The last week it has basically stopped filtering. Although there is still water coming out of the spray bar I'm pretty certain the flow is reduced. I read at another site that the little glass balls (eheim bio substrate - not the ceramic rings) have a great tendency to clog and that 2/3 of these should be changed out every 3 months. Is this what is going on? I did rinse them but really change them? Any ideas for changing the media around. Or using different media? FRUSTRATED.
