### ⭐⭐⭐⭐⭐ good replacment
*by J***Y on December 12, 2025*

Fit perfect, appears to be same that oriignally came with my flex but i misplaced the oem nozzle after replacing with a low flow one and needed to switch back.

### ⭐⭐⭐⭐⭐ Handy add on
*by A***Y on November 22, 2025*

Works well, got for a pre loved fish pond that was missing it and allows the water to stay in the tank now

### ⭐⭐⭐⭐⭐ Finally, An Easily Cleanable Spray Nozzle
*by C***S on January 16, 2024*

This must be my fifth spray nozzle purchased to try to improve the functionality of my Fluval Flex 15. I have Betta fish, and was trying to find a nozzle that did not create too much current. The problem is that when you get nozzles like that it’s very difficult to clean them. So I returned to the original item, and it turns out to be the ideal nozzle for this tank. It can be cleaned easily, and you can direct the current n ways so that it won’t affect fish that don’t like high flow. It’s made well, it’s durable and functional.
