Marineland PR2121 Impeller Assembly Emperor 400b Filter Parts for Aquarium

excellent product

works perfectly

This was a brand new in pkg impeller. It was like a rebuild of my filter system and made it much more efficient and quieter too.

The impeller broke due to low water in the aquarium a school that hasn’t been visited in months. Fish still alive! This replacement works great and now the tank is quiet! The same Marineland 400 has been in the tank since it was purchased which was a number of years ago.

Works great it quieted down my noisy filter. The shipping was a little slow but over all a good deal.

A++

Fix my filter by just replacing this.

It works in a marine land filter

We bought a whole used aquarium set-up through Craigs List - and the Emperor filter was noisy and weak. So we thought about replacing the filter, but many reviews said that replacing the impeller might just do the trick. The good news: like those reviewers said, it took a noisy, weak filter and made it quiet and powerful. Saved us quite a bit of money, at least until ... The bad news: Four months later, and its back to noisy and weak. So its another twelve dollars, and hoping that it lasts longer this time.

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