HAGEN AquaClear Waterfall Filter Description

These filters are well known and the AquaClear brand is highly recommended in the aquarist community.

They provide excellent filtration, near-silent operation, and legendary durability. Users regularly use these waterfall filters for years without any problems.

The unique design of the Aquaclear filter allows for a large amount of media to be placed in its large container. This increases the contact time between the filter medium and the water for more efficient filtration.

This large chamber also makes it more flexible when it comes to using filter media, allowing you to choose your favorite materials.

It comes with an efficient pump that minimizes energy consumption and therefore the cost of operation. The pump is designed to be energy efficient.

This is why aquarium lighting is what you have to take into account, you do not need to worry about the costs of having this filter working.

The fish tank water can be maintained in a proper and efficient way without the need for manual labor. This is thanks to its multi-stage filtration system.

This filter features the CycleGuard multi-stage biological filtration mechanism, which provides optimal chemical, biological, and mechanical filtration. It also ensures a constant cycle of beneficial bacteria to properly regulate the environment.

Its patented re-filtration system allows the flow to be reduced by up to 50% without interfering with the efficiency of the filtration. When the flow rate is lowered, the water inside the chamber is processed multiple times to make it ultra clean and maintain filtration efficiency.

Other opinions and criticisms of the AquaClear backpack filter

Everything you need to get this filter up and running is in the box, including filter media.

The media container of this waterfall filter is huge. Most backpack-style aquarium filters have media baskets, but the AquaClear filter has an open bin instead.

This allows you to use a ton and a half of material for better filtration. It also allows you to experiment with your media mix. The flexibility you have with this is a huge plus point.

Overall build quality is solid. It’s plastic, like most filters. Durability shouldn’t be a problem.

The action of the filter is quiet, but there is a slight noise from the lid hitting the top of the filter.

A problem that occasionally appears with Aquaclear filters is that the smaller models can suffer from flow problems. It can usually be remedied with a thorough cleaning, and usually only happens on the smallest model, but it can be a frustrating experience in a beginner aquarium with novice aquarists.

They have difficulties in self-priming. When the filters are unplugged or the power goes off, they may or may not restart automatically when the power comes back on. Because of that, the filter can run dry and burn out if not primed.

In case of saturation it can overflow out the back and drain the aquarium to the depth of the inlet tube.

Let’s see the advantages and disadvantages of Hagen ‘s AcuaClear backpack filter summarized in the most notable points.

AquaClear Filter Specifications

Let’s now see the main features of Hagen ‘s AquaClear filters.

efficient design

Although the AquaClear is a backpack filter, it uses a bottom-up flowing filtration design normally only found in external filters. This means that the water rises from the bottom, rather than trickling down from the top.

This way all the water passes through the filtration media. With this design, there is nowhere for the water to go but to flow through the filter media.

Also this filter has a large capacity for filter loads in a larger container than most cascade filters. It is very easy to set up thanks to the large and easily accessible compartment. In addition, it allows you to customize your own media mix to achieve the most optimal filtration.

The waterfall-style outlet agitates the surface of the water while creating beneficial currents through the entire volume of the aquarium.

AquaClear Filter Refiltration System

This filtration device also has a patented refiltration system that increases contact time by recycling water through the filter media. The highly efficient pump has a high flow rate and low power consumption.

CycleGuard Filtration

It is very easy to install, the sponge filter at the bottom, the activated carbon in the middle and the Bio-Max ceramic rings at the top.

The foam in this unit acts like a sponge in trapping dirt; and this is washable and reusable too. Click on this link to see this foam in the Amazon storefront.

The activated carbon filter, on the other hand, is useful in treating chemicals such as ammonia and other substances that may be present in the water. Click here to see charcoal on Amazon.

This unit is also equipped with the patented BioMax technology that allows the retention of beneficial bacteria in the water so that all of its inhabitants thrive well. Click on this link to see the BioMax on Amazon. If it is a new aquarium you will need the aquarium cycler to generate the bacteria colony.

Patented flow control

The Aquaclear filter includes a patented system for easy flow adjustment. Also, that you can regulate the intake and flow of water through this device to suit your needs and preferences.

AquaClear Cascade Filter Leveling System
