Compact, energy-efficient 3-watt internal aquarium filter with 4-in-1 functionality – combines mechanical filtration, biological filtration, chemical filtration and oxygenation in one ultra-quiet unit, ideal for small to medium freshwater aquariums from 5 to 65 litres (nano tanks, betta bowls, shrimp tanks, planted tanks or beginner setups). Delivers a gentle, adjustable flow rate up to 220 L/H to keep water clean and oxygen-rich without disturbing delicate fish or creating strong currents.
Key Features:
- 4-in-1 filtration system – multi-layer sponge traps debris (mechanical), hosts beneficial bacteria (biological), optional carbon insert for water clarity (chemical), and built-in air stone/bubble bar for oxygenation – maintains crystal-clear, healthy water with stable parameters.
- Ultra-quiet operation – advanced low-noise pump design (under 30 dB) ensures peaceful aquarium environment, perfect for bedrooms, offices or living rooms.
- Adjustable flow control – dial or slider lets you fine-tune water flow from gentle trickle (ideal for bettas, shrimp, fry) to strong circulation (for larger tanks) – prevents substrate disturbance or plant uprooting.
- 220 L/H flow rate – efficient turnover for tanks up to 65 litres; strong enough for effective filtration yet gentle for sensitive species.
- Internal mounting – suction cups or clips secure the filter discreetly inside the tank; compact size (typically 5–8 cm wide) fits easily in corners or behind decor without taking up swimming space.
- Easy maintenance – removable sponge cartridges rinse quickly under tap water; no frequent full disassembly needed – keeps beneficial bacteria intact for stable cycling.
- Low power consumption – only 3W – energy-saving for continuous 24/7 operation without high electricity costs.
- Safe & reliable – submersible design with sealed motor housing prevents leaks; no exposed moving parts that could harm fish.
Ideal For:
- Small aquariums (5–65 L) such as betta, goldfish, guppy, shrimp or nano community tanks
- Beginners or children starting their first aquarium
- Planted tanks needing gentle flow to avoid uprooting delicate plants
- Quiet home environments where noise from stronger filters would be disruptive
- Maintaining crystal-clear water with minimal maintenance
This 4-in-1 Boxtech internal filter offers excellent value with quiet, adjustable performance and comprehensive filtration in a small footprint – perfect for keeping your aquarium clean, healthy and peaceful with little effort.
