Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

good price.. worked great.. pump quiet now!

Bought as a spare, exact copy and part number

while the part came in and did work, it had little effect on improving the performance of my emperor400s. It was still loud with insufficient water flow.

This works great. My old impeller was noisy after the rubber pieces fell off and some parts were bent after years of service. After putting this in the filter system, started right up with much less noise almost like new.

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).

All my filter noise is now gone! I am so thankful

Makes one the bio-wheel filters that I have used, perform at its peek efficiency.

Reliable for many months!

It fixed my noisy Emperor 400.

The old one was worn out and extremely noisy. This one is very quiet.
