The brand is an AquaC RX-1. The issues are usually pump related(Eheim 1250), which should be a good pump. The impellars seem to wear out quickly 4-6 months. The other issue is sludge or "fines" that seem to get into the plumbing and end up clogging the pump. My media was not coarse enough last time and it seems to be an issue. The pump usually needs to be primed. It does it's job when running, the issue is keeping it running. Just curious if there is one that is more maintenance or in my case,idiot free.
