I never had a problem, 4 years and going strong, although I replaced my Eheim pump with a CSP-MAG. It never had any problems, I just wanted to go all DC-powered. It is beyond me how so many people has had problems with watercooling. To me it seems more reliable and maintenence-free even compared to standard aircooling. I cannot even imagine how watercooling can possibly have so many problems, thinking it is due to a lot of random circumstances rather than the idea of watercooling being inherently unreliable. In theory, and in my practice, watercooling if done right can be very reliable, quiet, and maintenence-free. In fact I didn't like the idea of refilling my res, so I built a humidity condenser to keep the res filled via moisture from the room air. Good stuff, you guys shouldn't have so many problems, really.
