I have two Eheim Pro 4+ 600 canisters on my 75G, using the stock media. They've been set up and running now for a few months. After the death of two juvenile oscars, the tank currently houses a JD, 5 silver dollars, 5 S. juruparI and 3 nerite snails.. All fish are juveniles, 3" or under. I feed 6 days a week, with Monday being a fasting day (and also my weekly water change day). So far, I have never cleaned the canisters.

Now, the issue...

Last week, one of the Eheims stopped working. Its on, and running, but its like when you turn it on without priming, where its not inputting or outputting any water.

So, while on and running still, I prime, and it starts right up again. Then its fine.

Today... the same Eheim does exactly the same thing. I look at the tank, notice the output is not outputting, so I depress the priming button a few times and it starts right up. So, stopped on me twice so far... within a 2 week period.

Anyone using the Eheim Pro 4+ series, and have similar issues? I'll eventually open her up and see if there's anything inside causing the problem, or air, or who knows. But, figured to ask here first. Maybe I'm missing something.

These filters are pricey. I hate that I have an issue with it already. Not to mention, I've never really been satisfied with the sucking power on the water intake... with any of the previous versions I've had. I like the filter, just wish they had more pull.
 
The one may be so filled with gunk, it is plugged up.
If you don't regularly clean the gunk out they will not run properly.
Beside that if you don't clean out the gunk, its still in your tank, just in an invisible chemical form, most noticeably as nitrate.

Yep, I understand that. But, the filters are newly set up. Besides the time it took to do a fishless cycle, they have only been running with fish in the tank since April 11... that's less than 2 months... and with small fish. I can't imagine that a canister with such a large volume, PLUS, there being two on the tank, be so gunked up in under two months that it should prevent it from running properly. If it were 6 months, even 4 months maybe... but if these are gunking up in less than 2 months, with the current stocking, that's not really an efficient filter.

I don't believe that its gunk in there. I am going to open it up and clean it out maybe next week, but I just was curious if this has happened to anyone else. I love Eheims, and trust them wholeheartedly. I've used Eheims from many many years. These Pro 4+ are the new ones I just picked up... that's why I'm a bit baffled.
 
Is the siphon for the intake breaking by chance? Evaporation in the tank?
