Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Pump works like new again. Last one lasted almost 10 years.

Our tank filter wasn’t working, and this fixed it.

My Emperor 400 was loud when I changed out the old propeller for the new propeller it got nice and quiet thank you

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

Im pleased and really liked this product.

Genuine part, works great

It fixed my noisy Emperor 400.

My 400 was never quiet from the start. After like 6 years, it was getting really loud so tried this. Now I just hear water from 3 feet away.

Pure joy replacing my noisy old impeller. Worth every penny!

Works great.
