Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Works perfectly it cut the filter noise to 0

Just what I needed to stop the rattling noise…thank you!

It is easy to install and uninstall for cleaning

exactly what I needed! thanks! fixed the issue with the filter and was less than 1/4 of the price to replace the whole thing

made a huge difference on an old filter, runs quiet again

Reliable for many months!

works good

My filter was super loud and this fixed it. It does seem to be a upgraded impeller.

This impeller stopped all the noise we had from the fish tank filter.

Had to replace due to my part breaking. Works perfect.
