UGF Box BJ-SH12 Under Gravel Filter

The UGF Box BJ-SH12 Under Gravel Filter is a simple and effective way to filter your shrimp aquarium.
This type of aquarium filter increases the available filter surface area by creating a flow drawdown through the substrate.
This results in the creation of beneficial bacteria, which are essential for maintaining stable water parameters and preventing anaerobic conditions.

UGFs are ideal for shrimp and fish tanks using an active substrate.
The active substrate provides a home for the beneficial bacteria, and the UGF helps to circulate the water and distribute nutrients throughout the tank.

Benefits:

• Simple to install and maintain.
• Effective at removing waste and debris.
• Promotes the growth of beneficial bacteria.
• Ideal for shrimp and fish tanks using an active substrate.

Note:

• When using fine media (>1-2mm), add a layer of larger media to ensure the UGF stays clean and prevents small media from falling into the lower chamber.
• No air stone is required.
• No filter media is provided.
