Atman HK-0600 Hang-On Filter

Powerful Filtration in a Compact, Space-Saving Design

The Atman HK-0600 is a compact and efficient Hang-On-Back (HOB) aquarium filter designed for planted aquariums, nano-to-medium-sized aquariums, and fish tanks where maintaining a clean and uncluttered appearance is important.

With a maximum flow rate of 720 L/H and only 6W power consumption, the HK-0600 provides strong water circulation while keeping energy consumption low. It hangs externally on the back of the aquarium, saving valuable space inside the tank.

Key Features

💧 720 L/H Water Flow
Provides strong circulation and continuous filtration, helping remove suspended particles and maintain clearer aquarium water.

⚡ Low Power Consumption — 6W
The efficient 6W motor provides a high flow rate without excessive electricity consumption.

🌊 Built-In Surface Skimmer
The integrated surface-skimming system helps remove unwanted surface film and oily residue, improving gas exchange and keeping the water surface cleaner.

🎚️ Adjustable Flow Control
The built-in flow control valve allows you to adjust the water output according to your aquarium's requirements. This is particularly useful for planted tanks, shrimp tanks, and aquariums containing livestock that prefer gentler circulation.

🧽 Multi-Stage Filtration
The filter combines mechanical and biological filtration using its included filter media. The mechanical media captures suspended debris, while the filter media provides a surface for beneficial nitrifying bacteria to colonize.

🤫 Quiet Operation
The motor is designed for relatively quiet operation, making the HK-0600 suitable for home aquariums, planted tanks, and display setups.

🔧 Easy Installation & Maintenance
Simply hang the filter onto the aquarium rim, prime the filter with aquarium water, adjust the flow and plug it in. The removable filter components make routine cleaning and maintenance straightforward.

✨ Space-Saving HOB Design
Because the main filter body stays outside the aquarium, the HK-0600 keeps the inside of your aquarium free from bulky internal equipment—ideal for aquascapes where appearance and swimming space matter.

Surface Skimming + Filtration

One of the biggest advantages of the HK-0600 is its combination of regular water filtration and surface skimming. The surface skimmer helps remove surface film, while the main filtration system continuously processes aquarium water.

This makes it particularly useful for planted aquariums where maintaining a clean water surface and good gas exchange is important.
