AquaClear Power Filter

The AquaClear Power Filter represents one of the most versatile hang-on filter systems available. The five models available provide a complete selection of flow rates for the most popular sizes of aquariums. The filter’s unique design allows for up to six times more media volume and the longest water to media contact time in the industry.

Superior Contact with AquaClear Filter
Patented Re-filtration System

Sometimes delicate fish and plants require a more gentle water flow. The patented AquaClear re-filtration system allows you to control the flow rate without compromising filtration efficiency. When the flow rate is reduced, up to 50% of the water within the filter chamber is processed multiple times.

CycleGuard Multi-Stage Filtration System

Provides optimal mechanical, chemical, and biological filtration. A healthy aquarium requires "beneficial" bacteria. Invisible and harmless, beneficial bacteria are essential in the removal of toxic ammonia and nitrite. With cartridge filtration systems, when you throw away the cartridge, you throw away beneficial bacteria. It can take weeks for the bacteria to re-colonize, resulting in a stressful environment.

Typical Filter Media Placement:

Bottom

AquaClear Foam Insert, which does the following: 1. Helps with debris removal and provides optimal water distribution patterns, allowing subsequent filter media to perform at full efficiency. 2. Biological filtration, due to the porous structure of foam, providing surfaces for beneficial bacteria.

Middle

AquaClear Activated Carbon Filter Inserts contain 100% premium research grade carbon. Premium research grade carbon provides large amounts of surface area for adsorption of undesirable impurities.

Top

AquaClear BioMax Filter Inserts contain BioMax ceramic rings. The surface of BioMax is made up of a complex pore system that allows bacteria to thrive.

AquaClear Power Filters
Power Filter Maintenance
  • For maximum filter operation and efficiency, regular cleaning of the filter and its parts is recommended every two weeks.
  • Always unplug the Aquaclear Power Filter prior to cleaning.
  • First you want to remove the cover, filter basket, and discard water remaining in the filter case. Thoroughly rinse collected debris from the case, impeller cover and impeller assembly using clear lukewarm water.
  • Then intake "U" tube and extension tube can be cleaned with a filter stem brush to remove any build-up of deposits.
  • When all parts have been cleaned and thoroughly rinsed, reassemble filter and replace any scheduled media. Install the filter once again back on the aquarium making sure that the filter is tipped slightly forward.
  • Then fill the AquaClear filter box with aquarium water. Finally plug the filter into an electrical outlet and the AquaClear will self-prime and begin running in a few seconds.
Media Replacement

AquaClear Foam Filter Insert: Replace Foam Filter Insert every two months. AquaClear Activated Carbon Filter Insert: Replace Activated Carbon Insert every month. AquaClear BioMax Filter Insert: Replace BioMax Insert every three months.

Warranty

Aquaclear 50 by Hagen aquarium filter. 200GPH

Aquaclear 50 by Hagen aquarium filter. 200GPH
12-7-2013 Update and some additional information:I moved my aquarium to another room the week 11/24/2013. When I moved the aquarium, I decided to clean the housing, impeller, and the cavity the impeller sits in. Up until this time, the AC 50 had been running quiet. However, after cleaning everything out, the impeller was making noise like it did when it was new. As of today (12-7-2013), this noise has been reduced by about 1/2. If things continue, the filter should be quiet again after the impeller builds up a slime coat. I also removed the undergravel filter from my aquarium. 12-13-2013 filter is quite again, just the sound of the motor running.I have been reading several negative reviews about this filter not priming itself after a power failure, filter cleaning, or a water change. One thing that appears to be an issue when reading these reviews is that the water level in the aquarium has gone below that of the top of the impeller cover. When the filter is turned off, the water level in the filter will become equal to the water level in the aquarium. If the water level is below that of the intake tube, the syphon will be lost and the intake tube will drain of water and the filter will not be able to start on its own without refilling the water in the filter. This is typical of many Hang Over the Back (HOB) filters.Sometimes, the impeller will fail to restart. This can be due to residue on the impeller shaft or on the magnet of the impeller. A good cleaning will usually remedy this problem. However, a long stick or skewer can be used to jump start the impeller if it fails to restart (this however only works if you are there to witness the problem). Any HOB filter that has a stuck impeller, and remains plugged in, has the risk of motor burnout.Another issue I see is that people are getting a AquaClear that is rated right at the size of tank they have, for instance a 20 gallon tank gets a AquaClear 20. This filter will filter a 20 gallon aquarium with minimal bioload, however the next size filter should be chosen. This would mean an AquaClear 30 and not the AquaClear 20 for a 20 gallon aquarium. I am personally using a AquaClear 50 on my 20 gallon and I am very happy with it. It is always best to have more filtration than needed rather than having too little or just the bare minimum.I am still very pleased with this filter and have no plans to change to another brand anytime soon.This review was updated on 12-25-2011.I purchased two of the AquaClear 50's on a buy one get one free deal. The price was right for the two filters and it gave me spare parts and extra media. The first filter was noisy from the impeller vibrating. I read various postings online about checking the impeller for damage, and manufacturing flaws. I also used petroleum jelly to lubricated the motor shaft, it was still very noisy from the rattling of the impeller. I removed the lid just to see if that made a difference, it did, but I could still hear the impeller vibrating from 15-20 feet away. It sounded like I was running the filter dry. I hooked up the second filter to see if it was any different. It still had a slight vibration/rattle, but it was not as much as the first one and was acceptable. I have been reading that this slight vibration/noise will go away in a month or so. After a week, the filter impeller started to quiet down and is hardly audible. I exchanged the noisy Aquaclear 50 for another Aquaclear 50.***Update: 12-4-2011: The filter is now quiet with just a hum of the motor running.***The small amount of noise coming from the current Aquaclear 50 has even subsided and is almost silent at this point. The lid does rattle from time-to-time, but it is not very loud.The Aquaclear 50 was hooked up on 11-25-2011. Today (12-2-2011) I had to clean the foam as it was matted on the underside with debris that had collected on it. I could tell it needed cleaning as the flow was somewhat slowed.My previous over the back filter was a bio-wheel 100. I have a 20 gal tank and the bio-wheel worked well when I first got it about 5 years ago. Over time I found myself getting annoyed with the bio-wheel stopping all the time. I also have an undergravel filter to help with biological filtration. When I saw the Aquaclear 50 on sale (buy one, get one free), I decided it was time to try something different than the bio-wheel 100. The Aquaclear 50 has double the flow rate (200GPH) than the bio-wheel 100 (100GPH) and is a much improved upgrade from the bio-wheel 100. Higher flow rates are available in the bio-wheel line as well, but I wanted to try another brand of filter.The water in my aquarium has not been this clean for a long time. I have not any problems with the filter not restarting after the power is has been shutoff. I did a few tests to see if it would restart on its own after being stuff off for 15 minutes and it always restarted. This could change over time, and I can see this being a problem if the water level in the tank goes below the equilibrium line of the filter and the tank's water level.I do recommend a pre-filter for the intake tube if you have small fish as the rate of intake can catch fish. I had this happen with one of my guppies and added a Fluval Edge pre-filter to the intake to prevent this from happening again.I like the ability to be able to rinse the foam insert in the filter without having to replace them entirely (although the manufacturer recommends every 2 months) unlike the bio-wheel system's filter cartridges. The foam insert can be cleaned many times, in conditioned water, to get the debris and to keep the nitrifying bacteria. The bio-max can also be rinsed in conditioned or tank water to allow it to be used longer. With the old bio-wheel I had to replace the filters every month due to the activated carbon in them. With the aquaclear I can run the filter without the activated carbon.Other than the noise of the first unit (which was exchanged), and to some extent the second unit (very little noise), I am very happy with it.The Aquaclear 50 comes with a foam insert, carbon filter, and bio-max media. There are two extension tubes that come with the filter. The filter is easy to assemble and attach to the back of the aquarium. There is an adjuster to level the filter with the aquarium that is located on the bottom of the filter.I am currently running it with two of the foam inserts and one pack of bio-max. I am debating on running only one foam insert and two bags of bio-max.Tank Size: 20 gallons.Current Filters: Aquaclear 50 and undergravel filter.Prior Filters: Bio-Wheel 100 and undergravel filter.Fish: 3 platies, 2 guppies, 4.5yr old angelfish, 4 albino corydoras catfish.Other: 3 ghost shrimp and 15-20 ramshorn snails.In my video I mention that the lid was a bit difficult to put on. It is much easier to put the lid on when the filter is actually installed on the back of the aquarium. It is not really an issue at all. Just something I came across while doing the video.

Any HOB filter that has a stuck impeller, and remains plugged in, has the risk of motor burnout.

Another issue I see is that people are getting a AquaClear that is rated right at the size of tank they have, for instance a 20 gallon tank gets a AquaClear 20. This filter will filter a 20 gallon aquarium with minimal bioload, however the next size filter should be chosen. This would mean an AquaClear 30 and not the AquaClear 20 for a 20 gallon aquarium. I am personally using a AquaClear 50 on my 20 gallon and I am very happy with it. It is always best to have more filtration than needed rather than having too little or just the bare minimum.

I am still very pleased with this filter and have no plans to change to another brand anytime soon.

This review was updated on 12-25-2011.

I purchased two of the AquaClear 50's on a buy one get one free deal. The price was right for the two filters and it gave me spare parts and extra media. The first filter was noisy from the impeller vibrating. I read various postings online about checking the impeller for damage, and manufacturing flaws. I also used petroleum jelly to lubricated the motor shaft, it was still very noisy from the rattling of the impeller. I removed the lid just to see if that made a difference, it did, but I could still hear the impeller vibrating from 15-20 feet away. It sounded like I was running the filter dry. I hooked up the second filter to see if it was any different. It still had a slight vibration/rattle, but it was not as much as the first one and was acceptable. I have been reading that this slight vibration/noise will go away in a month or so. After a week, the filter impeller started to quiet down and is hardly audible. I exchanged the noisy Aquaclear 50 for another Aquaclear 50.

***Update: 12-4-2011: The filter is now quiet with just a hum of the motor running.***

The small amount of noise coming from the current Aquaclear 50 has even subsided and is almost silent at this point. The lid does rattle from time-to-time, but it is not very loud.

The Aquaclear 50 was hooked up on 11-25-2011. Today (12-2-2011) I had to clean the foam as it was matted on the underside with debris that had collected on it. I could tell it needed cleaning as the flow was somewhat slowed.

My previous over the back filter was a bio-wheel 100. I have a 20 gal tank and the bio-wheel worked well when I first got it about 5 years ago. Over time I found myself getting annoyed with the bio-wheel stopping all the time. I also have an undergravel filter to help with biological filtration. When I saw the Aquaclear 50 on sale (buy one, get one free), I decided it was time to try something different than the bio-wheel 100. The Aquaclear 50 has double the flow rate (200GPH) than the bio-wheel 100 (100GPH) and is a much improved upgrade from the bio-wheel 100. Higher flow rates are available in the bio-wheel line as well, but I wanted to try another brand of filter.

The water in my aquarium has not been this clean for a long time. I have not any problems with the filter not restarting after the power is has been shutoff. I did a few tests to see if it would restart on its own after being stuff off for 15 minutes and it always restarted. This could change over time, and I can see this being a problem if the water level in the tank goes below the equilibrium line of the filter and the tank's water level.

I do recommend a pre-filter for the intake tube if you have small fish as the rate of intake can catch fish. I had this happen with one of my guppies and added a Fluval Edge pre-filter to the intake to prevent this from happening again.

I like the ability to be able to rinse the foam insert in the filter without having to replace them entirely (although the manufacturer recommends every 2 months) unlike the bio-wheel system's filter cartridges. The foam insert can be cleaned many times, in conditioned water, to get the debris and to keep the nitrifying bacteria. The bio-max can also be rinsed in conditioned or tank water to allow it to be used longer. With the old bio-wheel I had to replace the filters every month due to the activated carbon in them. With the aquaclear I can run the filter without the activated carbon.

Other than the noise of the first unit (which was exchanged), and to some extent the second unit (very little noise), I am very happy with it.

The Aquaclear 50 comes with a foam insert, carbon filter, and bio-max media. There are two extension tubes that come with the filter. The filter is easy to assemble and attach to the back of the aquarium. There is an adjuster to level the filter with the aquarium that is located on the bottom of the filter.

I am currently running it with two of the foam inserts and one pack of bio-max. I am debating on running only one foam insert and two bags of bio-max.

Tank Size: 20 gallons.
Current Filters: Aquaclear 50 and undergravel filter.
Prior Filters: Bio-Wheel 100 and undergravel filter.
Fish: 3 platies, 2 guppies, 4.5yr old angelfish, 4 albino corydoras catfish.
Other: 3 ghost shrimp and 15-20 ramshorn snails.

In my video I mention that the lid was a bit difficult to put on. It is much easier to put the lid on when the filter is actually installed on the back of the aquarium. It is not really an issue at all. Just something I came across while doing the video.

5.0 out of 5 stars My Favorite Aquarium Filter
Reviewed in Canada on October 3, 2021
The Aquaclear line of filters is my favorite for smaller tanks. They are easy to install, simple to clean and repair, and works really well. Make sure you get one that is generously sized for your tank. I installed the Aquaclear 50 on my 20g fry tank and added a sponge to my intake tube so that it doesn't suck up any babies. Despite the sponge, the motor is powerful enough to adequately draw water from the tank to maintain a good flow. It operates quietly too. Excellent choice for fish tanks under 100g.
