The Fluval Power Filter is designed to keep your aquarium water sparkling clean with five full stages of filtration. The extensive five-stage filter system includes two mechanical, one chemical and two biological filter chambers, while most filters only have one of each type. This filter is designed to trap large and fine debris and remove dangerous toxins all while cultivating good bacteria for a healthy environment for your finned friends. The mechanical filtration is performed by a thick poly/foam that traps debris. During the chemical stage, activated carbon removes toxins from the water. In the final biological stages, a Bio-Screen pad promotes healthy bacterial growth and contributes to fast and effective nitrification.
Extensive 5 stage filter helps to produce clean and clear water conditions and a healthy environment for aquarium life to thrive.
Provides maximum surface area and optimum dwell times in all stages of the filtration process.
Features 2 stage mechanical filtration that effectively traps large and fine debris, reducing harmful ammonia and phosphate build up by removing fish waste, uneaten food, and other organic materials.
Activated carbon for chemical filtration to effectively remove dangerous toxins while the Bio-Screen pad provides encourages the growth of good bacteria.
The patented refiltration control system lets you slow down the water output, creating a gentle flow to protect delicate fish and plants.
Using two of these in a 55 gal tank. Pretty quiet and does a great job keeping the water clean!
Fluval I'm so disappointed
on Jun 21, 2021
I purchased the Fluval C2 HOB 30 gallon filter to use on my 20 gallon guppy tank. At first it was great but within 2 months or so it started getting harder and harder to get it going again after being unplugged so to do water and filter media changes. 7 months later it can not, will not suck enough water up the tube to get going again at all any more. Had high hopes for fluval wanted to get the fx-4 for our120 gallon aquarium, but now refuse to spend $400.00 on a filter from this company after this let down. So so so dissapointed with fluval.
not good quality

I purchased this filter to try on one of my Axolotl tanks. Axolotls are very dirty creatures, and I figured the 5 way filtration would be better. Boy, was I wrong! The 5 way filtration means that each filtration chamber is tiny. So tiny, that it gets clogged with sludge almost immediately. In the few months that I was using this filter, I had to rinse out the filter sponges almost daily. And, with as quickly as it became clogged, it would stop filtering regularly, leaving my tanks looking yucky. This might be fine for a tank with a single fish, or a few less dirty fish, but definitely not for Axolotls.
Great hang on the back filter

This filter works great. It is a powerful filter that has multistage filtration action to keep my water clean. I only have a few minor complaints. The flow is pretty strong for some of my fish even at the lowest setting. My tiny clownfish likes to sleep on the top of the water and sometimes gets pushed By the current, like fish in a toilet bowl. I had to install a makeshift baffle out of a water bottle for now. Also I am a little worried that if the power goes out and I am not home that the bio rings will dry out and all the beneficial bacteria will die on them. The bio rings are only wet when the filter is turned on and then water runs over them.
Just meh and noisy

It’s an ok filter system. The aquaclear Verizon is better and more customizable not to mention more quieter. I wish I can return this after it being used for a couple of weeks. I tried every known trick to help with the propeller vibration noise. I bought the Fluval 207 canister for my 36G tank and it’s the best.
motor gets noisy in less than 6 months
on Feb 19, 2021
i bought this filter a little over 5 months ago and it was great, at first. it's rated for a 70 gallon tank and i'm using it on a 40 gallon. after about 3 months i started noticing the motor making a noise. i took everything apart and did a very thorough cleaning and worked well again for about 2 more months. when the motor started making the noise again, i did the thorough cleaning but the noise didn't go away this time. i guess the filter was only designed for a 6 month life. i am very disappointed as i've always had great experiences with fluval products being top quality. makes me question whether to purchase another fluval again as i'm typically a very brand loyal person.
Motor and Impeller lack Longevity
on Feb 16, 2021
I’ve been disappointed in the “long term” capability of this filter. I replaced my first one after 18 months of use with a second one in 2019. Now this replacement is operating similarly. The motor and or impeller assembly is now very noisey. Perhaps something is amiss internally or is out of alignment, but repeated assembly fails to correct the problem. Also getting the intake siphon tube lined up precisely over the impelled is hit or miss. Initially, these filters were superb, but once out of warranty, start saving your spare change for a replacement!
