Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Just as described. A+++++

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.

Works perfectly

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

Came on time and works perfectly! Filter noise down to zero!

Got my pump working again, what can I say! Need to replace this after 3/yrs of non-stop running.. wore this part out...

Quick delivery. Products great!

Have a Marineland Emperor 400 that was rattling loudly. Inspected the impeller and noticed it was worn and had some slop in it. Purchased this and BLAMMO! No more rattling! Just a nice water flow sound...ahhh....

works good thank you

perfect replacement for the filter
