Seachem Tidal Hang-On-Back Power Filter

About This Product

The Seachem Tidal Hang-On-Back Power Filter is a high-performance aquarium filtration system designed to deliver exceptional water quality, efficient circulation, and easy maintenance for freshwater and saltwater aquariums. Developed by Seachem, the Tidal series combines advanced filtration technology, adjustable water flow, and a large-capacity media basket to provide reliable filtration for aquariums ranging from 35 to 110 gallons.

Unlike conventional hang-on-back filters that rely on disposable cartridges, the Seachem Tidal features a spacious, customizable filtration basket that accommodates mechanical, biological, and chemical filter media. Each filter includes Seachem Matrix biological media and a reusable foam filter, providing an effective foundation for maintaining healthy aquarium water.

The innovative dual-intake filtration system draws water from both the aquarium surface and below the waterline. The integrated surface skimmer helps remove floating debris and organic films, while the submerged intake collects suspended particles from deeper in the aquarium. Adjustable flow control allows aquarists to customize water movement for different aquarium inhabitants.

One of the Tidal filter’s most convenient features is its self-priming pump, which eliminates the need to manually fill the filter before startup. The pump automatically restarts after a power interruption, helping maintain continuous filtration without requiring manual intervention.

The built-in maintenance alert provides a visible indication when filter media becomes clogged and requires cleaning. The removable media basket attaches to the filter lid for convenient transport, helping minimize dripping and spills during maintenance.

Designed for versatility and durability, the Seachem Tidal incorporates a corrosion-resistant, self-cleaning impeller, an adjustable leveling system, and an aerating water return that promotes oxygen exchange.

Whether you’re maintaining a freshwater community tank, planted aquarium, or saltwater marine system, the Seachem Tidal Power Filter provides powerful, customizable filtration in a dependable, easy-to-maintain design.
