I have an Eheim 2217 but it keeps clogging. This has started every since I added a pleco to the tank. The spray bar goes from full power to almost nothing in a couple of weeks.
I bought the filter off of craigslist. It came with a prefilter but for the life of me I cannot find instructions for it on the eheim site. Does anyone know the prefilter I am talking about? I will add pics.
Looks like I just put it on the intake.
