Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

My filter runs like new again! It saved me from purchasing a new filter.

Filter is quiet again. Took less than 2 min to change out and be up and running

It works in a marine land filter

Reliable for many months!

It did the trick and now my 400 works noise free and strong.I got this filter for $10.00 and all it needed was an impeller.So $10.00 for the filter and $14.00 for the impeller, thats $24.00 for a $60.00 filter.

My husband ordered this for his fish tank filter. It worked perfectly, and now the filter is doing its job without the loud noises.

Good replacement

My filter was super loud and this fixed it. It does seem to be a upgraded impeller.

Its great so far - my last one was rattling so loud, it drowned out the box fans I had going to cool the apartment. This is super silent and caused no problems with either the installation or operation.

Bought as a spare, exact copy and part number
