Fits Perfectly and Works Well
These bio-foam inserts fit exactly as expected and have been working without any issues. The foam is well made, holds its shape, and is easy to rinse and reuse. They’ve been a reliable replacement option and perform just as they should. No mess, no fuss, and no complaints. Simple, effective, and dependable.

Reliable and effective
I will always use fluval products in my aquariums and especially in all my filters. I recommend not putting off brand products in your filters. Very good value for the money!

Fast shipping
Love getting these from Amazon. They are a good price, comes fast, and are exactly what I need for my filter. They are easy to clean and swap out. They are perfect for my 125 gallon turtle tank.

Same pads for a year still. Durable.
Aside from the white coarse pads surrounding the trays, I run two of these black sponges wavy side up in all three trays and that's all. I detail my fx6 every six months and it handles the bulk of filtration on my 125. I also run a HOB for supplemental water polishing

Works great
It works great for my fluval FX2 filter. I have no issues. It came with my unit when I bought it new. Just needed to be replaced.

It is good and works perfectly fine in my FX5
It is good and works perfectly fine in my FX5. It is a bit expensive though! It comes in a nice box but I don't mind buying the foam pads in a cheap bag if this would lower its price. I'm throwing the box in the trash anyways.
