$11.89$16.99$19.03
Last update was on: Saturday, January 4, 2020

Size:Cascade 100

The Penn Plax Cascade Hang On Aquarium Filter features a revolutionary Bio-Falls Quad Filtration System to keep your tank clean and healthy. The polyfiber floss cartridge traps floating particulate matter while the activated carbon cartridge removes harmful chemicals, toxins, odors, discoloration and other contaminants from the water.

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.

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.

Aqueon QuietFlow Power Filters feature four stages of filtration – mechanical, chemical, biological and wet/dry – for the cleanest, clearest, healthiest water. Higher flow rates ensure higher dissolved oxygen content for healthier, more active fish. The internal pump design helps dampen noise, eliminates leaks and starts up automatically after cleaning or power interruptions.

Highlights
  • Auto-start, self-priming filter
  • Lifetime Warranty
  • No wheel to stop turning

Product Features

Higher Flow Rates

Aqueon filters have higher flow rates than the competition to ensure proper turnover for cleaner water and higher dissolved oxygen content, making fish healthier and more active.

Superior Biological Filtration

The patented biological grid has a large surface area to support more of the beneficial bacteria that eliminates ammonia and nitrates. A second wet/dry grid provides further biological filtration and oxygenation as the water returns to the aquarium.

Internal Pump Design

Since the filter pump is submersed in the aquarium, there is no need for priming at setup or when restarting the filter after cleaning or power interruptions. An internal pump also allows for virtually silent operation, continuous flow raters, less chance for leaks, and a much thinner profile.
