Review: Usual great Fluval product - Excellent just what you expect from Fluval. Outside packing was damaged but item was fine.
Review: Easy fit - This was easy to fit, as a replacement to the original one in my FX4. The original was failing (or so I though). However. After fitting the new one. The flow was still poor. It turns out, that for the 2 years that my FX4 has been running with my 350ltr tank. Whilst having a media wash every 3 months. I had been inadvertently missing out cleaning the one in the middle of the lower basket. And it had restricted the flow. So I now have a spare impeller for when the new one wears. My training is now complete!

### ⭐⭐⭐⭐⭐ revived a failing FX4
*by M***R on 26 December 2022*

I didn't realise you had to replace the impeller on the Fluval FX4 every 12 months so mine has been running for over 3 years with the same unit however it started to slow down so i bought this kit and replaced the impeller also worth knowing mine came with impeller ceramic shaft and seals also worth mentioning you need some silicone grease its a must now ater 20 mins of running its back up to being a fully working filetr again i would buy from this seller every time i have also bought a spare for next time it runs out as the prices of everything is going up
