Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

Dusted off my OLD Marineland Emporor 400 and it was unbearably loud. Had to sleep with the bedroom door shut - so bad. I replaced the impeller with this one and it cut the noise in half, at least. Still not silent but normal. Side by side, the top and bottom rubber/plastic bits on the old impeller had worn down noticibly. Worth this $25 to save an old, reliable aquarium filter and the cost of replacing it!

This is the 3rd impeller Ive had for this filter in about 8 years. They seem to wear faster than impellers on any other brand of filter, but they also do a great job of cleaning. I believe sand and this impeller are simply not a good mix; stick to aquariums with gravel.

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

I received this product is a timely manner. I bought this item for a back up so I have not used them yet.

Better than the original. Great purchase for my tank

I bought this thing after trying lubricant on my old impeller. I had no success in making my old one quiet down. I had it about 2 years I guess. I installed this one and the difference is amazing! I be if I added a little lube I wouldnt hear anything but water. Worked perfect in my Emporer 400. Highly recommend this for anyone with noise problems.

This thing is Great, my original impeller was causing my filter to become noisy and was barely pumping water through the spay bars making the bio wheels move very slowly. Once I replace the old impeller with this on I noticed a huge difference. My water was back to curculating properly and the filter has become completely silent, it wasnt this quiet when I first bought it. Great replacement product.

Work perfectly!

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....

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