Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Fast shipping! still working 6 months later.

Better than the original. Great purchase for my tank

Pump works like new again. Last one lasted almost 10 years.

Works perfectly it cut the filter noise to 0

My old impeller wouldnt stop making this horrible clattering and grinding noise no matter how many times I cleaned it. I assumed it was worn out and needed to be replaced. Happily, the new unit works like a charm! Its as quiet as can be.

This was a super easy fix for my noisy pump. Read a review that laid out my same problems 2 days later fixed. Super happy with this purchase.

This impeller was just what I needed! It was easy to replace and my filter is now working like new!

Worked GREAT! Good price!

perfect replacement for the filter

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