The filter delivers a strong flow rate while remaining energy-efficient and quiet. With space for multiple filter media types, it supports mechanical, biological, and chemical filtration to maintain excellent water quality in freshwater or marine aquariums.
3-Stage Filtration System
The SunSun HW-602B features a multi-layer filtration system that allows mechanical, biological, and chemical filtration. This helps remove debris, harmful toxins, and excess waste from the aquarium water.
Strong Flow Rate
The filter delivers a powerful flow rate of approximately 400 liters per hour (106 GPH), ensuring proper water circulation and oxygenation inside the aquarium. This makes it ideal for small tanks and planted aquariums.
Suitable for Small Aquariums
This compact canister filter is recommended for aquariums up to 20 gallons (around 75 liters), making it perfect for nano tanks, shrimp tanks, betta aquariums, and small community fish tanks.
Compact & Space-Saving Design
The small external design allows the filter to be placed outside the aquarium, saving space inside the tank while providing stronger filtration compared to many internal filters.
Customizable Filter Media
The canister has space above and below the filter pads where you can add additional media such as ceramic rings, activated carbon, or bio balls to improve biological filtration performance.
