The valve I have has a rubber disc which is pushed by water pressure so the water can flow around, and contributes significantly to head loss.
Even without the check valve, the Eheim is adequate for circulation but doesn't contribute much to flow. So I'll be trading in the Eheim for a Mag 3 unless anyone can tell me where to buy a Quietone 1200 or assure me that the Rio 1100 is not crap.
Saltysurfer, are you sure about the Liquidtight? It looks like a white PVC core with grey coating (nylon??) inside and out. Should keep water in as well as out. Definitely not metallic--requires a ground wire for electrical applications. I would prefer something a little more flexible, though.

That conduit should be alright, Some of the flex conduit is metal coated in plastic. Sorry to alarm you. BTW nice tank!
