FluvalFX Carbon Foam, Replacement Aquarium Filter Media, 2-Pack, A249,White

I'm very pleased with Fluval products and the Nitrite filters are a very effective and affordable way to keep your fish healthy and happy.Remember to use their other filters in conjunction with this filter as well. Carbon filters, ceramic bio filters and polishing filters are all required for the Fluval canister filters.

Made my tank clearer this helped alot very happy

This, along with several of the other Fluval resin pad products, is a need for my aquarium! I have a Fluval FX4 for my goldfish tank, and these pads work perfectly to help decrease all the ammonia they excrete. Great product! Love how they come in packs of three. Will be buying often.

I put two of these in my FX6 and it makes a noticeable difference after several water checks with aquarium co-op test strips the differences night and day I would definitely recommend and I will be buying these again

A hardcore ehiem fan for 35 years, it was a slow progression over to the FX5 of which I now run three. The filter are beasts especially if you keep messy fish you see the pay off almost immediately. Still an ehiem fan and swear by their build quality but when you can you buy three FX5's for the price of one 1200 XL - and that's without media it's a no brainer.They both have pro's and con's I find the FX5's far too dependant on mechanical filtration, when those pieces of foam load up with gunk not only does your GPH suffer but water parameters become unstable. In an established tank there's enough nitrifying bacteria in your media and substrate to maintain the delicate eco system in your tank.The foam however should just be tossed and replaced. Keep in mind it takes TWO packages for a complete foam change. Hagen which owns Fluval has been notorious for decades in over hyped non certified flow rates, the push for replacing and selling media and positioning products like a simple replacement foam which leads the consumer to think it's an all inclusive deal. Why they don't give you all the foam you need and up the price or vice a versa and let you know up front only half of what you need is included.Thank's to a another reviewer I knew to order two packages per filter X 3 - you do NOT want to leave half of the dirty foam in your filter. Clogged foam only increases water bypass, trapped air and a significantly reduced flow rate.Aside from that, the foam is good quality. If I had the patience I would simply buy my own foam sheets and cut it myself. I do the same with 800 micro polishing pads but for me it's not about saving a few dollars and everything about crystal clear, pristine water.The price on Amazon is by far the best I've seen. I added a few boxes or blue and white coarse and fine pads and the total with 2 day Free shipping via my Prime membership was under $100 - about a 20% saving over the big aquaria e-commerce sites.

What i ordered and recieved fast!

The media could not be loaded.  I’ve always use generic brands since the Fluval brand was expensive. Now with this price Im stocked up! And my tank is crystal! Love these quick clear pads!

I USE THESE PADS EVERY TIME I CHANGE MY TURTLE'S TANK.

Merci

Fits an FX6 perfectly.
