Fluval Flex Total Upgrade Kit – Protects Baby Fish & Shrimp and Makes Maintenance Easier (Fits 9G and 15G Tanks) Shrimp Intake Covers

Fluval Flex Upgrade Kit – Intake Covers, Feed Hole Cover, and Lid Kickstand for Fluval Flex 9 Gallon and 15 Gallon Aquariums

The problem this solves: The stock Fluval Flex aquarium design makes it easy for shrimp, fry, and small fish to get pulled into the filter intake. This can lead to stress, injury, or livestock loss. The strong flow from the filter can also be difficult for delicate species, and the original lid design does not stay open on its own, making routine maintenance awkward.

This Fluval Flex Upgrade Kit solves several common issues for Flex owners in one simple package. The kit protects shrimp and baby fish from the filter intake, helps manage water flow without reducing filtration performance, reduces evaporation through the feeding hole, and allows the aquarium lid to stay open during maintenance. Designed specifically for the Fluval Flex 9 gallon (34L) and Fluval Flex 15 gallon (57L) aquariums, this kit improves safety, stability, and ease of maintenance.

What is included in the kit:

Intake covers for Fluval Flex filters
One of the most common problems with the Fluval Flex aquarium is the open intake area that can pull in shrimp, fry, and small fish. These precision-fit intake covers block entry points while maintaining strong water flow. This helps protect livestock in shrimp tanks, breeding tanks, and nano fish aquariums without reducing filtration performance.

Feed hole cover to reduce evaporation
The open feeding hole in the Fluval Flex lid allows moisture to escape, which can increase evaporation and require frequent top-offs. This feed hole cover fits securely over the opening to help retain humidity inside the aquarium. Reducing evaporation helps maintain stable water parameters, which is especially important for shrimp tanks and planted aquariums.

Lid kickstand props for hands-free maintenance
Holding the Fluval Flex lid open during feeding, trimming plants, or cleaning the aquarium can be frustrating. This kit includes canopy kickstand props that hold the lid open securely so you can use both hands while working in the tank.

Two lid prop sizes are available:
XL props approximately 8 inches tall, ideal for feeding and light maintenance
XXL props approximately 12 inches tall, ideal for aquascaping, cleaning, and deeper tank access

Once installed, the kickstand supports the lid safely and keeps it open without needing to hold it or lean it against a wall.

Protects shrimp, fry, and nano fish from filter intake

Reduces evaporation and helps maintain stable water levels
