Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Exactly what I needed

Bought as a spare, exact copy and part number

Worked! My filter works like new. Pumps water quietly and has good flow rate. Saved me the cost of a brand new filter!

Works with Emperor 400

Good replacement

Bought to replace original Impeller in Emperor 400 Pwr Filter - new on Aug/2019 . (Only 2 1/2 years old) New Impeller did fix no water flow to spray bars issue. Also ran very quiet. (Well see how long this Impeller lasts.) Somewhat over priced. (Also see Youtube re repair Impeller by glue. Also tried this & it DID work).

It fit, but might be a bit noisier than the original impeller.

Perfect replacement part. Filter is extremely quiet now.

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!

Worked perfectly, I was worried I had to replace the whole filter. Im so glad I researched and found this.
