Zanyzap 6 Carbon Impregnated Foam Pads for Fluval FX4 / FX5 / FX6 Canister Filter

It may have a light layer of some carbon but its really just a average foam pad that is a waste of money and space. Use the space for something else.

Great filters fit my FX6 perfectly

Great value

These pads work great for our filter

Bottle came opened and damaged my other staff

Works as well as my old system of charcoal in bags and takes like 99% less time to change the filter. Worth the higher cost to charcoal.

I am very happy with my purchase!

Just as good as Fluval brand, 6 for the price of 2 Fluval. Also a good fit in canister.

Ok

Suitable replacement foam pad for my Fluval FX6 filter
