Hang on filter 401

The Hang‑On Filter 401 is a compact and user‑friendly aquarium filter system designed to clip onto the back of small freshwater tanks, nano aquariums, betta bowls, and desktop fish tanks. Featuring a hang‑on‑back layout, it draws water from the aquarium, passes it through filter media, and returns clean, oxygenated water — all while saving internal aquarium space.

This HOB filter is ideal for hobbyists who want efficient mechanical filtration, surface skimming, and improved water clarity without complicated installation. The lightweight design and simple clip‑on mounting make this filter perfect for beginners and small tank setups.

Key Features:
✔ Compact hang‑on‑back design — installs easily on the aquarium rim without taking up interior space.
✔ Effective mechanical filtration — traps debris, uneaten food, and waste.
✔ Water circulation & aeration — promotes oxygen exchange and a healthier aquatic environment.
✔ Ideal for small tanks — suitable for nano setups, betta, shrimp, and small community tanks.
✔ Adjustable or waterfall flow options (depending on model) help you tune circulation to your tank’s needs.

Usage Tips:

1. Clip the filter securely onto the back of your aquarium.

2. Ensure the water level is sufficient so the intake stays submerged.

3. Rinse or replace media regularly to maintain peak filtration.

4. Periodically check for blockages to ensure smooth water flow.
