don't get me wrong, when my berlin turbo classic is working like it should, it can pull some muck out of the water. just seems like it's becoming a decent size pain in my *ss lately. i was BS'ing with the guy who owns a lfs in my area and he showed me the euroreef he's running on one of his tanks, it was pretty wicked.
anyways, what exactly is wrong with your pump? it's not working at all? have you tried cleaning the impeller and the housing out? i try to take my pump apart and clean it once a month or so. i don't really have a problem with the pump stopping, my problem lies in the airline clogging with salt creep. i've tried shortening and lengthening the tubing, it still finds ways to clog, on the average of once a week.
