I just got a new external Eheim 2213, and I'm really struggling to prime it (the sucking way).
It's kinda running ok I think, but I can hear there some air trapped in there. I've tried gently rocking the filter, but after numerous attempts, it's still not quite right.
I also have an 2224, but that's no problem to prime as I just open on of the little "arms" and throw water down the pipe.
But I just struggle with this 2213
