I've been checking out the new penguin filters and was wondering if any one has any experiences with them. I currently have a 20gal w/ a Emperor 280. I have to dismantle the filter about once a week, if I don't the propeller starts to make a grinding sound when I shut the flow down for feeding. It really is an annoyance I was like to get away from. I like the bio wheels but I've heard the original penguins were horribly noisy. So I was wondering if they fixed that with the redesign?
