Fluval FX4/FX5/FX6 Bio-Foam, Replacement Aquarium Filter Media, 2-Pack, A239

I use the Fluval FX5 filter for a 125 gallon RES turtle tank. For anyone out there that knows anything about turtles the are messy! With that said since I switched to the FX5 my tank has never been so clean and I dont have to clean the filter nearly as often as any other filter I have used on this tank in the past 4-5 years.

Great product!

Exactly what I needed instead of going to the store.

This oem replacement works like it should by removing the finer particulates the larger pads dont. I added 2 of these polishing pads and a bag of carbon/ammo chips to the bottom basket of my FX6 and the water is sparkling clear on my planted aquarium. Once the pad starts to fall apart when cleaning, its time to replace. I recommend that these pads are replaced at that time and avoid trying to get more life out of it by placing it above the newer pad as some aquarium forum posts suggest as it may clog the newer pad as it falls apart.

These have been great keeping my tank clean and water crystal clear. Make sure you get enough to change your tank filter system at least once a month.

Well if you have seen any of my reviews about Fluval or Seachem products, you undoubtedly will come to a conclusion that I only use those 2 products & I buy in bulk for the best price or use Amazon Subscribe & Save. Why? Because they work plane and simple, I have seen the off brands at great prices and even gave them a shot, while the off brand is a bit thinner they do a decent jobI I found that at least in my setups (multiple very large tanks and heavenly stocked African Cichlids and SA/CAs which are very very large and messy fish) the off brands clogged up a bit faster. I am a fantic when it comes to maintaining my tanks. I run a total of 5 Fluval FX6 filters (2 in my African 135 and 3 in my 220 CA/SA along with 3 Fluval FX4 in my other 3 tanks from 30 to 90 gallon) These polishing pads really trap and polish the water combined with The White Fluval pads and water is crystal clear giving the illusion my fish are floating on mid air. These filter pads work in many other canister filters as well with very little effort. Bottom line if you run any of the Fluval FX series these pads are a must and are worth every penny!

Ive used this pad in the top tray of my FX6 for awhile now with great results. It helps filter fine particles out of the water that may have otherwise been missed by other media.

works on my fx4 thank you

Use this product all the time for Clearwater I. Fish tank!
