About this part

An open-top Flex 32.5 shows off the tank, but the rear filter chambers stay open. Water evaporates faster, and dust, food and leaves drop into your media. These three chamber lids close the rear chambers and give the back of the tank a clean, finished edge.

Compatibility
  • Fits: the Fluval Flex 32.5 gallon (123 L), when you run it without the stock lid.
  • Does not fit: the Flex 9, Flex 15 or Flex 2.0.
Why it helps
  • One middle lid and two outer lids cover all three chambers.
  • Less evaporation and less dust in your media.
  • Deep cutouts let cords, airline and hoses pass to the back.
  • Lift one lid to reach one chamber; the others stay in place.
Installation
  1. Use the angled edges as your guide: the middle lid has two straight and two angled edges.
  2. Set each lid on its chamber. Sturdy tabs hold it in place.
  3. Route your cords through the cutouts.

I wanted to go lidless with my 33.5 gallon Fluval Flex so I wanted something to cover the filter area without cutting or modifying the lid and I came across these. These little lids fit perfectly, are very durable, are pretty much seamless with the aquarium aesthetic, and were shipped super quickly. I'm not sure I could have expected more.

I bought the back covers for a Fluval Flex 32.5 and I could not have asked for anything better. Overall the quality is awesome, and they fit perfect. Also the price is fantastic for these. I was so impressed that I bought the back covers for my Fluval Flex 15.
Thank you for making just what I was looking for!!!!!!!!
