Well, I couldn't get my Berlin Turbo working right, it kept on leaking water....which wasn't a good thing. I have read that the Berlin are supposed to be good, but I didn't want to try another one. I was thinking about either a AquaC EV90, a CPR-SR4. I have a 72gal. Anyone have experiences with any of these? I was leaning towards the AquaC because of the good reviews I have read.
