Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Too much for an impeller replacement

Better than the original. Great purchase for my tank

Quieted down my Marineland Emperor 400s significantly! Replace that old, worn out, and noisy impeller.

It is easy to install and uninstall for cleaning

Super easy to replace and works like its brand new. I have a video on YouTube on how to replace it

Works just great!

Just as described ! Great shipping time !

It is exactly what it says. I bought a used Emperor 400 filter and the old impeller was bent which made the filter extremely loud. This one fit perfectly and has made the tank far more enjoyable for my ears and also for my fish who are now getting proper filtration.

Just a perfect fit

It did the trick and now my 400 works noise free and strong.I got this filter for $10.00 and all it needed was an impeller.So $10.00 for the filter and $14.00 for the impeller, thats $24.00 for a $60.00 filter.
