Marineland SP1850 Magnetic Impeller Assembly for Penguin PH1140

Replacement Impeller for the Marineland Penguin Powerheads. The impeller is what makes the filter system work, and is commonly the root of filtration problems due to lack of cleaning and maintenance. Clean the impeller and the rest of your filtration system regularly to avoid problems, and prolong the life of your impeller and filter system. The impeller can be found at the end of the water intake tube in the back of the filter compartment.
