Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Just as described. A+++++

I little than expected, but still fit. Works well and QUIET, which is what the old one wasnt after 12 years of use.

Like others have written one of my Emperor filters was slowing down flow quite a bit. Part arrived and after installing the impeller it was like night and day. Very quiet and works great so I am getting ready to purchase a second one for the other filter. By the way, it got here in record time for paying regular shipping fee! Couldnt be happier with this product...

Perfect fit, installs easy. Fixed noisy filter, Emperor is running perfect again.

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

So happy I bought this! I have a 15 year old Marineland Emperor 400 on the original impeller. Decided it was probably time to change even though the original was still moving water. Now the filter REALLY moves some water. So happy!

Fit perfect.

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

perfect replacement for the filter

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