Fluval basket questions, answered straight.
Which Fluval tanks does the basket fit?
The rear chamber of the Fluval Flex, Spec, and Evo. Each product page names the exact model and chamber its basket is made for.
How do I know the basket fits my chamber?
Each basket is made for the chamber named on its product page. Match your tank model and chamber number, and that is your basket.
What media goes in the basket?
Fill it with your own carbon, bio media, or filter floss. It is an open basket, not a copy of a branded cartridge.
How does the basket come out for cleaning?
A flared lift rim makes it easy to grab and pull straight out of the chamber.
Does the basket fit the Fluval Flex 9 and the Flex 15 the same way?
No. The Flex 9 and the Flex 15 have different chambers, so each one gets its own basket. Pick the one named for your tank.
