Fluval 207 Performance Canister Filter

The Fluval 207 is the smallest canister in Fluval’s current Performance series, made for aquariums up to 45 gallons. It sits in the stand below the tank and runs water through stacked media baskets before sending it back up.

Quiet and efficient

Fluval’s eTEC pump design is built for strong, steady pressure while drawing about the same power as an LED light bulb. Fluval says the pump runs up to 25% quieter than the earlier model. In a bedroom or living room tank, that matters.

EZ-Lift media baskets

The media baskets stack inside the canister, and a center handle lets you lift the whole stack out with one finger. That makes maintenance faster and less messy. A typical stack goes foam first, then bio media, then a polishing or chemical layer.

Picking the right size

• Fluval 207: up to 45 gallons.
• Fluval 307: a step up for larger tanks. See our Fluval 307 page.
• Fluval 407: for bigger tanks still. See the Fluval 407.

Setup tips

Put the canister below the tank so gravity helps it prime. Use the priming steps in the manual, then check the lid and hose connections for drips over the first day. Loosely pack bio media like Fluval BioMax so water passes through it, not around it.

Maintenance

Rinse foam in removed tank water every few weeks, replace chemical media on schedule and leave the bio media alone as much as you can. Lubricate the lid O-ring now and then.

Who should look elsewhere

For a small tank where you’d rather not run hoses, a hang-on is simpler.
