I was putting some new material in my eheim cannister filter and (besides a big messup that resulted in mucho spilled water) I've been unable to get the siphone going since. It will start up, the fan will go into overdrive, then poop out, and start up again a few minutes later.
Is there an old thread here or a web site with a diagnostic check that I can do to go through reason this might be?
Thanks, guys.
