would this be a problem? like ive heard that these filters are relly noisy. i like the design of these guys. i bet these are really good, but im wondering if the filter will make too much noise for me to sleep at night? i had an aquaclear 110 and it made so much noise, it sounded like a really loud hummmmm constantly, even with the lid off. i couldnt stand it so im wondering if this will be along the same lines. note i heard from some the old emperors differ from the newer models- i would be buying a newer model. thanks
