About this part

The Flex 9 intake chamber takes water from two intakes, and many baskets block one of them. This 4-stage media basket uses side-stacked compartments, so water from both intakes flows in freely and then passes through every stage of your media.

Compatibility
  • Fits: the original Fluval Flex 9 gallon (34 L), chamber 1 (the intake chamber).
  • Does not fit: the Fluval Flex 2.0 or the Flex 15.
Why it helps
  • Up to 4 stages of media; you choose what goes in each one.
  • Side-stacked compartments keep both intakes open.
  • Five pieces: a bottom spacer, a top basket and three removable divider plates.
  • Pairs with our 3-stage center chamber basket for a full Flex 9 setup.
Installation
  1. Drop the bottom spacer into chamber 1. Check the direction in the photos.
  2. Load the top basket and the three divider plates with your media.
  3. Set the top basket in, so its tabs push into the grooves of the spacer.
In the box

This filter media chamber makes another purchase from this shop that I’m really satisfied with - it’s well made, fits together easily, and works very well. I’d been debating whether I really *needed* a filter upgrade, since my tank has only a betta and some snails, but this product let me add some sponges, filter floss, and a large bag of ceramic biomedia, and it’s already made a difference less than 24 hours later. My tank was clear before, but now it’s approaching crystal clear, and the effect is beautiful. Also, because of the extra bio media, I’ll be able to remove some and transfer it over when I set up my next tank to kickstart the cycle. I would highly recommend this product; my betta had a bad case of fin rot, and after that scare I felt it was important to add extra filtration to manage free-floating bacteria. Thanks!

This is a must have, Item is well made and sturdy. I was able to load my favorite bio media and easily slot it in place. There is extra room at the top that is useful for bio media that is too big to fit in the shelves.

Slid right into place like it was an OEM part. I bought this with the three media basket, and now I can use both chambers to ramp up the media in my filtration.

I'd say these were a must-have for any Flex owner.

Dieser Artikel ist wirklich wunderbar er passt wie angegossen in mein Becken hinein so wie auch angegeben und wenn man z.B. kein Interesse an altertümlichen filternden hat kann man auch ganz eifach die Trennwände weglassen und biologisches Filtermaterial im netzt einfüllen. Mal sehen wie mein Becken sich entwickelt.
Sehr schönes Detail so nebenbei das das Logo des Unternehmens mit in die Seite reingedruckt ist. Das Material gibt keine unangenehmen Gerüche von sich wie das bei manchen 3D Druck Materialien kennt.

Tolle Arbeit!

Fit perfectly and was very easy to install. All I had to do was remove the intake covers to slide it into place and then pop them back on. The water is clearer than it’s ever been. Great upgrade to any Fluval Flex!
