The Fluval Intake & Output Kit for 307 & 407 Canister Filters is the genuine intake and output kit for Fluval's 307 and 407 canister filters — the tubes, strainer and rim hardware that live inside the tank.

Key Features

• Fits the Fluval 307 and 407 canister filters
• The in-tank hardware takes the abuse: strainers get brittle, tubes get scratched, and clips break when a tank is rescaped
• Sold as a set, which is usually cheaper than replacing the pieces individually
• Made by Fluval, the aquatics brand of Rolf C. Hagen, which has been building aquarium filters since 1975

Fitting It

• Unplug anything electrical before putting your hands in the tank
• Disconnect the hoses and take the unit to a sink rather than working over the tank
• Check the old part against the new one before fitting. If they differ, stop and check the model number
• A smear of silicone lubricant on an O-ring before reassembly makes the next service much easier and helps the seal sit properly
• Prime the filter and watch the first few minutes of running for leaks before you walk away

Good To Know

• Check the model. The 107 and 207 use smaller parts and these will not fit
• A cracked intake tube draws air and stops the filter priming, and the crack is often too fine to see
• A sponge pre-filter over the strainer protects shrimp and small fish and keeps the intake clear
• A genuine Fluval spare part. Check the model number against your unit before ordering — Fluval part numbers look alike and do not cross over between series
• Fluval sells these individually so a filter can be repaired rather than replaced, which is usually the cheaper and greener option
• Keeping a spare impeller and O-ring in the cupboard saves a tank when something fails on a weekend
