Query: Shake Rattle and Roll

I acquired a used Fluval 305 which did a love of 'shake, rattle and rolling' every time I turned on the pump. I inspected the impeller and noted that the plastic portion of the impeller had been damaged. With the replacement impeller in place, the pump is now singing Silent Night. It also helped to improve the water flow of the pump! I feel for a small investment I have extended the life of my 305. I have been using Fluval cannister filter and products for over 20 years, and will continue to do so as long as they continue to offer quality products.
