The problem this solves: The stock Fluval Flex feed hole is open by default, which leads to three common issues-excess evaporation, fish jumping into the lid chamber, and an untidy appearance. It also allows dust, debris, or curious fingers to get into the tank, and doesn't provide any way to control humidity buildup under the lights.
The Vented Slide Cover solves all of these problems in one sleek, functional upgrade. Custom-designed to fit the feed opening on both the 9-gallon (34L) and 15-gallon (57L) Fluval Flex models, it offers a secure, stylish way to seal the opening while still allowing airflow and easy feeding access.
💧 Why This Cover is a Must-Have:
✔️ Perfect Fit for Fluval Flex 9G & 15G
Slides neatly over the stock feed opening with no gaps or shifting. Precision-cut for a seamless look and reliable function.
✔️ Reduces Evaporation
Minimizes water loss caused by open access to the air. Helps maintain consistent water levels and reduces the frequency of top-offs-especially important in shrimp tanks and planted aquariums.
✔️ Keeps Fish In and Debris Out
Prevents fish from jumping through the feed hole into the back filter chamber or out of the tank entirely. Also keeps floating debris, dust, or uneaten food from getting into the opening.
✔️ Slide-Open Feeding Access
The vented lid slides open smoothly, making daily feeding quick and mess-free. No need to remove the whole cover-just slide, feed, and close.
✔️ Vented for Airflow
The integrated vents allow fresh air circulation while reducing condensation and heat buildup under your lighting system.
✔️ Choose Your Look - Black or White
Available in two clean, modern color options to match your tank's lid and create a unified, polished appearance.
✔️ Made from Durable, Aquarium-Safe Material
Constructed from non-toxic, high-strength plastic that's easy to clean, resistant to warping, and built for long-term underwater exposure.
💧 Ideal For:
Fluval Flex 9G and 15G owners looking to minimize evaporation
Preventing jumpers like Betta, Rasboras, or small gobies from escaping
Clean, organized nano tank setups
Aquascapers who want a better, more practical feed lid solution
A small upgrade that makes a big difference in both function and appearance, the Vented Slide Feed Cover is a must for any Flex owner who wants better control over their tank.
