How To Customise a Fluval FX6 Filter!

Today I’m upgrading my Fluval FX6 canister filter using a full range of Seachem media, including Matrix, Purigen, De*Nitrate and PhosGuard. I take you through everything I picked up, how I organised the baskets inside the FX6, and the full step by step setup of the upgrade.

This video shows the entire process from removing the old media, fitting all the new Seachem products properly, and getting the filter running again. The difference in water clarity afterwards was honestly massive! The tank looks cleaner, sharper, and overall a lot healthier.

If you’re running a Fluval FX Filter, this exact setup will work for your filter too. Whether you’re trying to improve biological filtration, reduce nitrates, or just get clearer water, this upgrade is definitely worth considering.

Let me know in the comments what media you’re using in your canister and if you’ve tried any of these Seachem products!
