Fluval Flex/EVOXII/Spec XV Nozzle Set – Directional Flow Outlet for Improved Water Circulation – Compatible with 9-16 Gal Fluval Aquariums

I saw the price on this thing and wondered if I could use it for my return line with my Cobalt EXT Canister filter. The barb attached to this nozzle is a 1/2" female threaded to probably 1/2" barb. Now, my 5/8" ID is pretty thick (came with Cobalt Filter) and it fit snug, plus it's inside the tank so I don't really mind if any water leaks out. You can definitely get a different sized threaded female barb but keep in mind this thing is small, like it fits in the palm of my hand and the output nozzles are small and the opening slant is narrow. For my needs this worked perfectly because I wanted a more controlled water flow for my little fishies. overall, this is a good nozzle set to buy if you know what you need it for or would use it for!

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.

This is the perfect replacement for my tank's pump connector.

I attached it to the filter pump. It fit, functions as intended, no leaks, not broken.

As it was desrcibed and on time

Awesome

Item was very small for what I needed it for but nonetheless was of great quality. Had to return due to item being too small for my output

Good value, especially if you're building an AIO tank or just want to upgrade your return nozzle
