I'll tell you what:
DO NOT BUY THE EHEIM ECCO SERIES
I replaced this filter not even A WEEK AGO. I had a minor issue tonight with my tubing, the filter ran dry for less than an hour(everything was cool when I went to the gym, not fine when I got back), and the replacement's pump is spent.
I can't believe. I CAN'T BELIEVE IT!.
I will never even consider the ECCO again, EVER!.
I'm still an eheim man, but it's the classic or Pro II for me.
I understand that running dry is an extreme condition, but IT HAPPENS, and I expect a top of the line pump to survive.
