About this part

The stock Flex return shoots water out in one strong, straight jet. Bettas and other long-finned swimmers end up fighting that current all day. This fountain output nozzle splits the flow into five gentle fountains that spread across the surface, so the water keeps moving while your fish buddies get a calm place to swim.

Compatibility
  • Fits: Fluval Flex 9 and 15 gallon (the original, 34 L and 57 L) and the Fluval Flex 2.0, 9 and 15 gallon.
  • Does not fit: the Fluval Flex 32.5 gallon. It has its own fountain nozzle.
Why it helps
  • Five soft fountains in place of one hard jet: a gentler current for bettas, shrimp and small fish.
  • The water still moves across the whole surface.
  • Pushes onto the 1/2 in ball socket that is already in your tank. No adapter needed.
  • About 200 mm wide and 53 mm tall.
Installation
  1. Pull the stock Y-splitter off the ball socket on the back wall.
  2. Push the nozzle onto the ball socket until it sits firmly.
  3. Fill the water to the groove between the main pipe and the fountains. That level gives the smoothest flow.

Works great and adjusts the flow so there is very little disturbance in sand. Thank you.

This was a perfect fit for my fluval aquarium. it creates a perfect flow for my shrimp tank that does not send my shrimp sailing across the tank.

The filter fountain nozzle is a great product if you need to lessen the flow in your Flex tank. I did have to modify it, because my Betta was still getting blown across the tank.
I tucked a piece of filter floss in 3 of the 5 nozzles. I still get flow from them, but it is much more gentle, and the other 2 provide good surface agitation for the tank. Great product!

This is the perfect solution to keep my betta happy in his Fluval Flex. Shipping was super fast, and the product is well made. It was easy to install and works perfectly. My little betta and I are very happy!

This calmed my water return enough that I could increase the pump volume without blowing my gouramis away. Excellent product. Easy to install. I’m buying another one!

Great addition for shrimp/betta tank.

This is exactly what my betta needed to be happier. The stock spray bar made way too much water flow and kept blowing him around. This keeps the water moving but nice and calm for him to swim.

This and a lower flow pump has created the ideal gentle flow my nano fish and Neocaridina shrimp appreciate. Thank you!

This was the perfect addition to my Fluval Flex aquarium to get the flow to slow down but still provide enough aeration in the tank. Highly recommend.

This new outflow water fall adapter fit perfectly and was so easy to install. I’ve already seen an amazing improvement in tank activity as the fish have started finding new areas to explore. I have Killi Clown fish and Chilli Rasboras who are now able to take full advantage of the tank and plants.

This piece was bigger than I thought it was going to be but despite that it was easy to install and serves its intended purpose! overall great purchase.

It’s super duper cute! Went onto the round piece easily and stays in place all on its own. Makes only a small amount of noise, so it’s perfect for my pristine display tank! The best part is that it came two days earlier than expected! A great little fountain that is made well for a frankly INCREDIBLE price. Highly recommend to anyone with a fluval flex tank of the right specifications.

Fits my fluval flex 2.0 15 gallon perfectly! My betta seems to like the slower flow as well. Just ordered another one for my other tank!
