I have a Pro 3,2080. The Pro 3's may look cool,but that is about it. They are poorly designed,and do not work half as well as a Classic. A 2080 is good for a 75 gallon,and that's about it. A pretty expensive filter for a 75. I also have a 2262,excellent,excellent filter. Eheim Classics are great filters, don't waste your money on the Pro models.
