Inlet Strainer with Ball Valve Fluval for 305/405 306/406 models (A20008)

The Fluval Inlet Strainer with Ball Valve is a replacement intake component designed for use with Fluval canister filter models 305/405 and 306/406. It combines a protective intake strainer that prevents debris and small organisms from entering the filter with an integrated ball valve for straightforward flow adjustment. This part is intended for freshwater and planted aquariums where intake protection and simple regulation of water flow are needed to maintain safe and effective filtration.

Advantages

The inlet strainer reduces the risk of clogging and protects delicate inhabitants by blocking leaves, substrate grains and other debris at the filter intake. The integrated ball valve allows easy, gradual control of flow rate without having to reach the filter body, enabling quick adjustments during maintenance, livestock changes or plant care. The design is compatible with the specified Fluval models, fits directly on the intake tube, and is made to withstand normal aquarium conditions.

Suitable for

• Freshwater aquariums with moderate to heavy biological load
• Planted tanks where reduced intake flow protects plants and small fauna
• Setups where easy, on-line adjustment of circulation is required
• Owners seeking a simple replacement intake part for specified Fluval canister models

Key specifications

• Component type: intake strainer with integrated flow control valve
• Material: aquarium-grade plastic suitable for freshwater use
• Function: prevents debris entry and provides manual flow adjustment
• Compatibility: designed for the corresponding Fluval canister intake tubing and models
• Installation: inline attachment on intake tubing, tool-free connection

How to use

Install the inlet strainer on the intake tube according to the filter manufacturer’s instructions, ensuring a secure, leak-free connection. Position the strainer inside the aquarium away from direct contact with substrate to minimise clogging. Use the ball valve to adjust flow: rotate or move the valve mechanism gradually to increase or decrease water intake until the desired circulation is achieved. Periodically remove and inspect the strainer for trapped debris and rinse under aquarium water during routine maintenance to maintain optimal performance.

Usage recommendations

Check the intake strainer regularly for accumulated debris and rinse with tank water as needed rather than tap water to preserve beneficial bacteria. When performing major flow adjustments, monitor tank inhabitants and plants for stress and adjust gradually. Replace the part if plastic wear or damage compromises the seal or valve function.
