Hi All,
Just set up a new Eheim 2217 on my 55 gallon tank and I'm wondering how
to
connect the Eheim prefilter I purchased separately. The "upside down J"
intake tube that comes with the filter does not reach to the bottom of
the
tank when connected to the pre-filter. The pre-filter, OTOH, comes with
two
tubes, one straight about 10" long, another narrower with a curve at the
end, which is too small for the wide intake tubing of the 2217. So
there is
no clearly obvious way that I see to connect the prefilter using
existing
plumbing parts.

Before I go cutting into things I thought I'd ask here how the prefilter
is
supposed to connect.

Thanks for any input,
Howard

I use a eheim prefilter with my 2215 by inserting the J shaped piece
(that came with the filter itself) into the base tube of the prefilter,
the one with the rubber coupler. But I think the base tube of the
prefilter might be the same size as the J tube of your filter. The only
solution I can see would be to join the base tube of the prefilter and
the J tube that came with your filter with a 1" or 2" piece of the hose
that came with your filter. You might have to cut down the J tube though
so it wont stick out of the top of the tank too much. I'm not sure if
this would work, as I'm not sure of the hose, and tubing sizes of the
2217, but it's the best plan I could come up with using your existing
materials. Hope this helps, good luck.

Correct, hence the problem....

Ok. I cut a small piece of the 10" piece that came with the prefilter, put
that in the prefilter, connected it to the J-tube with a 2" piece of tubing
and the Eheim is prefiltering as we speak. Good stuff.

Thanks much,
Howard
