Filter Replacement Parts and Accessories Emperor 400 Impeller (mfg# PR 2121)
A great filter!
I have used Marineland filters for several years. I am currently running two Emperor 400 filters on my 90 gallon saltwater tank and running a 350 on my 55 gallon planted tank. I am going be adding another 350 to the 55 gallon. These filters are easy to maintain and trouble free.

I like biowheels, they do a great job converting ammonia to nitrate. I also use them to breed Tanganyikan killiefish, they like to lay their eggs in crevasses, and the folds in the filter work as a substitute just fine; place them on the bottom of the tank.
