Aquaclear Hang on the back Summary

The Aquaclear Power Filter series is a fantastic filtration system that comes in all shapes and sizes for most standard aquariums. It is one that I have used in the past and plan on using for future aquarium builds. It provides biological, chemical, and mechanical filtration for your fish tank and has a media basket that is quite customizable. This article will go into detail about each Aquaclear HOB Filter.

Aquaclear 20 A-595

The Aquaclear 20 Power Filter is rated for fish tanks between 5 and 20 gallons. You can check it out on sale at Amazon by following this link. Out of the box, this power filter comes with foam sponges, activated carbon, and BioMax. The AquaClear 20 filter flow rate is roughly 100 gallons per hour (378 liters per hour) at its maximum. You can adjust the flow of this filtration system to fit your needs. The minimum flow rate is 33 gallons per hour (125 liters per hour). This HOB filter has a media basket that allows you to swap out filter media with ease. AquaClear branded media is available to make switching out filter media incredibly simple. This model’s filter media will have a large 20 labeled on the box.

I would recommend purchasing bulk media such as activated carbon and foam sponges. Those are things that will more than likely need to be switched out over time. You may not require ammonia remover if you have an established fish tank. An established fish tank should not have increased levels of ammonia. If you own loose filter media, you can purchase AquaClear 20 Nylon Bags to add your filter media.

AquaClear 20 Dimensions

This filter is small and compact but still provides plenty of power to keep your fish tank clean! The AquaClear 20 dimensions are 4 7/8″ x 4″ x 5 3/4″ (LxWxH). If you’re using the metric system to measure the dimensions they are 11.75cm x 10.25cm x 14.75cm. Most of the filters will hang on the outside of the aquarium. The only piece inside the fish tank will be the intake tube. This allows you to have plenty of space for aquascaping!

How Much Electricity Does AquaClear 20 Use?

The AquaClear 20 does not use much electricity at all. When running this little filter will use 6W. This isn’t too much energy considering a filter is a fairly important tool we use in fishkeeping.

Fluval AquaClear 30 A-600

The AquaClear 30 Hang-on Filter is rated for aquariums up to 30 gallons. You can check out the Aquaclear 30 on Amazon. This model comes included with a Foam Sponge, Activated Carbon, and BioMax. The AquaClear 30 Power Filter has a little more power to it than its smaller counterpart. The AquaClear 30 flow rate will max out at 150 gallons (568 liters) per hour and has a minimum flow rate of 50 gallons (190 liters) per hour. Similar to other AquaClear filters this one has filter media specifically designed to fit its media basket. You will see a large 30 on filter media boxes rated for the AquaClear 30.

This HOB filter also has a media basket that allows you to mix and match different filter media. There is AquaClear branded media available to purchase to make your life easier. The filter media is appropriately sized to easily fit into your filter. This model’s filter media will have a large 30 labeled on the box.

AquaClear 30 Dimensions

This filter has a little larger footprint compared to the AquaClear 20. The only difference in size between AC20 and AC30 is the length. The AquaClear 30 dimensions are 6″ x 4″ x 5 3/4″ (LxWxH). For anyone using the metric system, that is 15.25 cm x 10.25 cm x 14.75 cm. This is a filter that is just a little larger but benefits from an increased flow rate and more space for filter media.

How Much Electricity Does AquaClear 30 Use?

It might be surprising, but like the AquaClear 20, the AquaClear 30 also only uses 6W of energy. With this filter, you get more surface area for biological, chemical, and mechanical filtration and more water flow.

Fluval AquaClear 50

The AquaClear 50 filter is designed for aquariums of up to 50 gallons. Check it out on Amazon here. This filter model will come included with AquaClear Foam Sponge, Activated Carbon, and BioMax. The AquaClear 50 flow rate will max out at 200 gallons (757 liters) per hour. On the other hand, it can be dialed down to have a minimum flow rate of 66 gallons (250 liters) per hour. So far each filter increases the max flow rate by intervals of 50 gallons per hour. The pump will intake water which will feed through the filter housing. Like the other AquaClear hang-on filters, the housing will have a media basket that will help provide mechanical, biological, and chemical filtration.

AquaClear 50 Dimensions

AquaClear 50 dimensions will remain roughly the same as the smaller models. The only thing larger with this model is the length. AquaClear 50 Power Filter is 7″ x 4″ 5 3/4″ (LxWxH). If you prefer seeing these measurements in centimeters, they are 17.75cm x 10.25cm x 14.75cm. Overall, it is not much larger than the AquaClear 30 but benefits from providing more flow and more surface area for filter media.

How Much Electricity Does AquaClear 50 Use?

Similar to the smaller hang-on-the-back models, the AquaClear only uses 6W of energy. This filter might be a little overkill for smaller fish tanks, but it may still be great for 20 or even 30-gallon aquariums.

Fluval AquaClear 70 A-615

The AquaClear 70 is rated for aquariums up to 70 gallons. Pick it up on Amazon by following this link. However, if I have an aquarium this large with a well-stocked fish tank I would consider using a canister filter and maybe supplement the fish tank with this filter. Heavily planted aquariums will probably get by with an AquaClear 70 but fish tanks with high-bioload fish will, in my opinion, require something more.

Anyway, the AquaClear 70 flow rate will max out at about 300 gallons (1135 liters) per hour. You can adjust the flow and at its minimum, this filter will pump water at about 100 gallons (380 liters) per hour. This filter increases the flow rate in the aquarium by 100 gallons per hour, compared to the AquaClear 50.

It comes included with Activated Carbon, Foam Sponges, and AquaClear BioMax. When hunting for filter media replacements look for AquaClear boxes with a large 70 labeled on them.

AquaClear 70 Dimensions

We see an increase in length, width, and height for the AquaClear 70 dimensions. The AquaClear 70 is 8 1/4″ x 6″ x 8″ (LxWxH). For our friends that use the metric system, the dimensions are 21cm x 15.25cm x 20.5cm. That is a fairly large increase in size which will help your aquarium become filtered successfully. Remember, you can’t really over-filter your aquarium!

How Much Electricity Does AquaClear 70 Use?

The AquaClear 70 only uses 6W of energy. It’s a little much for smaller aquariums but great for 40, 55, or 75-gallon fish tanks. If the flow is adjusted, it may work on a 30-gallon aquarium.

Fluval AquaClear 110

We have finally gotten to the largest AquaClear Power filter. The AquaClear 110 Filter is a behemoth. You can pick up the AquaClear 110 Filter on Amazon! It is rated for aquariums up to 110 gallons. The AquaClear 110 flow rate will max out at 500 gallons (1890 liters) per hour! At its minimum, this power filter will output water at 166 gallons (630 liters) per hour. As stated above, I would personally choose a canister filter if I have a large bio-load over a power filter of this size. Luckily, in this hobby there is no single correct way of doing something right, so do what works best for you.

This power filter model will come included with Activated Cabon, BioMax, and Foam sponges. When shopping for filter media, replacements for the AquaClear 110 will have a large “110” label on the box.

AquaClear 110 Dimensions

The dimensions for the AquaClear 110, are larger than all of the other models. This hang on the back filter is 13 1/2″ x 6 3/4″ x 9″ (LxWxH). For metric system visitors that translates to 34.5cm x 17.25cm x 23cm. This provides plenty of space for filter media and plenty of surface area for beneficial bacteria.

How Much Electricity Does AquaClear 110 Use?

The AquaClear 110 power filter uses a little more electricity compared to the other models. This model uses 14W of energy. It is not incredibly more but just know that it does consume a little more electricity.

AquaClear Instructions & Installation

The AquaClear hang-on filter is incredibly easy to install. After opening the box, you can remove the filter media from inside the housing. Make sure that all plastic wrapping is removed. I have known new aquarium keepers that tried running the filter with media still wrapped in plastic packaging. You can start putting the filter together. Here is how I would recommend installing your AquaClear filter:

  1. Prepare Filter Media inserts (rinse carbon, transfer BioMax, etc.)
  2. Install filter media inserts in the media basket and place the media basket into filter
  3. Attach the Intake U Tube to filter
  4. Attach the Leveling device
  5. Mount power filter onto aquarium & adjust leveling device
  6. Add water into Power Filter Housing, and fill the housing with water
  7. Plug the power cord into the electrical outlet

Here is an AquaClear manual that shows the specs, parts list, and instructions for AquaClear filters. The manual also provides a list of replacement parts and troubleshooting information at the end, including tips on what to do if your AquaClear filter is not working.

Final Notes

Hopefully, this article helps give you a rundown on the different AquaClear models and you can decide which will work best for you.
