Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

1

Genuine part, works great

I bought this thing after trying lubricant on my old impeller. I had no success in making my old one quiet down. I had it about 2 years I guess. I installed this one and the difference is amazing! I be if I added a little lube I wouldnt hear anything but water. Worked perfect in my Emporer 400. Highly recommend this for anyone with noise problems.

This impeller is excellent. Have had it installed only 4 days so far, but since the second I installed it, it has been whisper quiet. Even more quiet than I remember the original being on the first day I hooked up the filter. I would definitely recommend if your original filter impeller is getting uncomfortably noisy.

I was about to throw away the old emperor 400 filter due to the constant grinding and sucking sound it was making. I decided to buy this impeller for it just to see if I could fix it and sure enough the filter works perfectly! Super quiet

thanks to this little piece, i dont have to put the TV volume up to level 40 anymore...it did quiet down the whole filter. theres no more rattling and vibration noise. i will update if anything changes. so far...its been worth the purchase (2 weeks)

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

Fix my filter by just replacing this.

I would have bought these at the same time I bought my filters if I knew what kind of difference they would truly make. It is crazy how much quieter my filters are now that I replaced the impellers with these bad boys. Talk about a world of a difference! I highly recommend these for any body that has a loud filter. I have sand as my substrate inside of my aquarium and it is always getting caught up in the filters, the stock impellers could not handle it but these have no problems and are still completely silent after two months of owning them. Definitely worth the purchase, they will make a world of a difference in your house!
