Fluval Flex Betta Bar Also Fits EVO Spray Bar: Even Flow, Reduces Fish Stress (9G/15G/32.5G/16G) Reverse Flow Is BestFREE SHIPPING!

The problem this solves: Stock nozzles in Fluval Flex and EVO tanks often create narrow, high-pressure currents that can stress sensitive fish like Bettas and shrimp. This strong, uneven flow also causes dead zones in the tank where water stagnates, reducing oxygen levels and circulation efficiency.

The Upgraded Spray Bar solves these issues by distributing flow more evenly across your aquarium. It attaches directly to the original ball joint of your Fluval Flex or EVO tank and channels water through multiple openings to create a smooth, balanced current—without reducing your filtration system's gallons-per-hour (GPH). Whether you need strong agitation or a calm, gentle flow, this spray bar gives you better control over your tank’s water movement.

💧 Available Flow Styles:
✔️ Regular Flow – Maintains strong output and increases surface agitation, helping boost oxygen levels in tanks with active fish or high bio-loads.
✔️ Low Flow – Breaks up flow into a softer, more randomized pattern that reduces stress for Bettas, shrimp, and planted tanks.
