hygger Aquarium HOB Filter 105 GPH | External Hang-On Back for 10-20 Gallon Tanks with Adjustable Flow

Experience reliable water movement with the Hygger Aquarium HOB Filter. Designed for 10-20 gallon tanks, it delivers up to 105 GPH to boost circulation and oxygenation without cluttering your tank. The external hang-on design keeps your tank clean and accessible, while the gentle waterfall return creates a soothing ambiance as it circulates water.

Effortless setup and maintenance

The HOB construction lets you mount the filter outside the tank, freeing valuable display space and reducing disturbance during maintenance. A quiet, ambient flow comes with a subtle trickle sound—enough to indicate active circulation without overpowering the tank’s atmosphere.

• External hang-on design saves tank space and minimizes disturbance during cleaning
• Quiet operation with a natural mini-waterfall return
• Up to 105 GPH max flow for effective circulation in small to mid-sized aquariums

Adaptive flow and flexible fit

Adjust the water flow with the top knob to match your tank’s inhabitants and stocking level. The intake tube extends to fit deeper tanks, ensuring consistent filtration from top to bottom. An inlet sponge helps prevent small fish or shrimp from being drawn in, adding a layer of safety to your setup.

• Top knob adjusts flow to suit tank conditions
• Extendable intake tube accommodates varied tank depths
• Inlet sponge reduces accidental intake of small creatures

Filtration media you can customize

The filter ships with two media options that you can mix and match as your aquarium matures. The cartridge uses dual-sided sponge cotton paired with ultra-activated carbon to trap debris, odors, and discoloration. The bio-filter plate provides a larger surface area to support beneficial bacteria. You can easily add or replace media to tailor filtration to your needs.

• Cartridge with sponge cotton and activated carbon for solids and odors
• Bio-filter plate offers enhanced biological filtration surface
• Replaceable media supports ongoing customization for beginners and experienced hobbyists

Overall, this Hygger HOB filter is built for practicality and adaptability. It pairs straightforward setup with adjustable flow and versatile media options, making it a potential fit for many 10-20 gallon setups. While performance will vary with tank mates, feeding routines, and overall tank maturity, the design emphasizes ease of use, flexibility, and a tidy, unobtrusive filtration solution.
