FX5 Filter Foam Block - 3-Pack

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.

Well if you have seen any of my review's about Fluval or Seachem product's, you undoubtedly will come to a conclusion that I only use these 2 product's & I buy in bulk for the best price. Why? Because they work plane and simple, I have seen the off brands at great price's and even gave them a shot, while the off brand does a good job, I found that at least in my setups (multiple very large tanks and heavenly stocked Cichlids African 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 Blue 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 ate worth every penny!

Great filters were great. Water is crystal clear

Great sponges for bacteria growth for fancy goldfish in my 112 goldfish tank. I only need to clean it every couple of months and replace them twice a year.

Good premade products. I would give 5 stars but I have a lot of filters so I buy it by the roll and cut to size.

Filter works well. Keeps the clear.

Fuval has good filters

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!
