If you're using a Fluval Flex 9 or 15 gallon aquarium, you already know it's an awesome all-in-one tank—but once you start customizing your layout, one problem becomes clear fast: the bottom intake. Want to build up a thick gravel bed? Add rockwork? Go all-in on a planted aquascape? That low intake starts working against you—pulling in gravel, disturbing shrimp, or even getting blocked by your substrate.
That’s where our Snorkel Intake Cover comes in.
What It Does (and Why You'll Want It)
This custom 3D printed intake cover is designed to cover the bottom intake of your Fluval Flex while still allowing full water flow. It raises the intake point up into the water column, which means:
-
You can build much higher substrate without worrying about gravel clogging your filter
-
Shrimp and fry stay safe, because they’re not getting pulled into the back chamber
-
You still get steady, effective water flow—just smarter and safer
It’s a simple swap that makes a huge difference, especially if you’re keeping delicate species or want more freedom in your aquascape design.
What’s in the Set?
Each kit includes:
-
Top Intake Cover
-
Bottom Snorkel Intake Cover
You can choose between two flow styles to match your setup:
-
SLIM: Tight slits for max protection (ideal for shrimp tanks)
-
MAX: Wider slots for stronger water flow and faster turnover
Both styles fit perfectly without glue or tools—just press them in and you’re done.
Perfect for Shrimpkeepers & Aquascapers
If you’re raising neocaridinas, caridinas, or nano fish, this is hands-down one of the smartest safety upgrades you can make. And if you love building lush, layered aquascapes? This is your chance to go deep on substrate without compromising your filter setup.
Compatible with Fluval Flex 9G & 15G (and Fluval Evo)
