3.0 out of 5 starsGood - but new buyers be aware: Needs *2* for a full foam change
By Steve from Brooklyn on June 8, 2012
Verified Purchase
This product is sold specifically for the fx5, and yet only comes with half the needed pads. A bit misleading. The pads serve very little biological purpose in a properly set up canister, and when you do want to replace them, it makes most sense to do all of them. Someone simply shopping for pads for their fx5 would buy this product, but nowhere does it say you'll need 2 boxes to get the appropriate number of pads.

For what it's worth - you can get your own coarse foam in sheets or rolls from the LFS, and cut it to size and save a ton over this stuff anyway.

4.0 out of 5 starsPerfect For A Full Foam Exchange - Misleading Advertising
By Peter Suslock TOP 500 REVIEWER on June 4, 2013
Verified Purchase
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.Read more ›

2.0 out of 5 starsOver priced..

I found a seller that sells 12 filter pads for $20 through Zanyzap;) and when I ordered through them I got 24 filter pads vs the 12 that I ordered. These are the correct size filter pads for my Fluval FX5 and shipping was on time, but I can't see myself paying this much for filters again..

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 don't have to clean the filter nearly as often as any other filter I have used on this tank in the past 4-5 years.

5.0 out of 5 starsit is what it is
By SAW dust on March 18, 2009
Its foam, it filters!
I do have a suggestion for shipping these foams. I got a box at my front door and I think to myself, what did I buy that requires a box sooo big??? I open it and to my disbelief its my foam filters for my Fluval FX5 canister filter. The shipping box was at least twice as big as the boxes the foam comes in. Plus it was protected with what seemed to be yards of crumpled brown paper. All of this waste was real disappointing. ITS FOAM ! Its not going to get hurt in transit.
I suggest that Whoever ships these filter foams, Please, just tape the box or boxes together and throw a shipping label on it. Really, thats all it needs. PLEASE do not let anyone ship this item to you the way I just received my filters today. Its a sickening waste of paper products. Thanks!

4.0 out of 5 starsUse it until you have enough experience to tinker (3-6 months) and then maybe still use it
By Joseph M. Cohen on April 10, 2011

If you have a FLUVAL FX5 then you are familiar with this stock part. If you are buying an FX5 for the first time, or have recently purchased one; use this stock replacement foam for at least the 1st six months.

There are great mod's for the FX5- but get a feel for the quirks of the filter before tinkering :-)
