Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

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).

Just a perfect fit

This was a brand new in pkg impeller. It was like a rebuild of my filter system and made it much more efficient and quieter too.

OEM quality and it worked perfectly. So far so good and i was certain i wouldnt have a problem anyway!

Worked great for our needs. The unit was starting to sound really loud and it even stopped working a few times and Id have to play around with it to get it the filter to start working again. I replaced the impeller with this one and its worked perfectly quiet ever since.

It fits

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

My Marineland Emperor 400 filter had become extremely noisy. Tried the vaseline trick to quiet the rattling noise but was unsuccessful. Finally decided to buy a new impeller. Replaced the impeller and no more noise. Works like its supposed to work. No complaints.

The impeller I had before was the original when I had bought the filter unit a few years ago. replacing it with this new one made the filter super quiet again and works even better on my 80 gallon tank. Transaction was great - got it very quickly

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