I had to clean my Eheim Pro 3 350 in a hurry tonight as it seemed to be totally clogged (virtually no flow). The bla5ted thing took me over an hour to get going again; I only managed it by continually pouring water in through the inlet and outlet pipes and then running it; doing the same; again; and again. The silly priming pump thing on the top just seems to move a bubble in the top of the inlet u-bend backwards and forwards without achieving anything. What could be wrong? I'm tempted to junk the whole thing after tonight's performance.
