Create surface ripples and gentle water flow with the Aquario Neo Reliever. Designed for Aquario Neo Flow Lily Pipe systems, the Neo Reliever attaches to the outlet pipe to diffuse water flow instead of directing it in a single stream.

The adjustable design can be rotated to customize flow direction for your aquarium. Angle it slightly upward to create gentle surface agitation for improved gas exchange, or pair it with the Neo Skimmer for extra surface skimming. It’s an excellent option for aquariums with shrimp, bettas, nano fish, and other livestock that prefer calmer water movement.

Reviews

Awesome product!

"Really like the design of this product, and how easy it is to customize it to your tank. I’ll definitely be using this moving forward."

Christopher H. (5/5)

Works great !

"I love this Neo acrylic products . Easy to swap out outlet parts to adjust the flow and no worry of breaking them like the glass outlets . I feel a lot more relaxed when I use these and have to clean them plus they work very well . I especially like the inlet shrimp protector piece . It’s easy to clean and my little shrimp never get sucked up through the inlet tube openings ."

Good lily pipe

"I like the aquario neo lily pipes as the acrylic is more flexible and I’ve broken my share of glass lily pipes in the past. It comes with a little remival diffuser for the middle of the lily pipes in case flow is too strong. Depending on positioning the outflow will also gently agitate the surface."

Neoflow

"I really like these pipes, but there are two down sides. The bracket is finicky, and the plastic can be brittle especially the elbow piece. If they could reinforce the elbow joint and use a different bracket design these would be perfect. Still its worth it to me to not have to worry about breaking a pipe while cleaning. The flow is good and the skimmer is easy to adjust."

"knew this was gonna work but didn’t expect it to work this good. really calmed down my cannister’s output for my 40g betta and tetra tank. fits perfectly in an Eheim classic’s outlet pipe"

Lou (5/5)

Neo Flow

"Using the Neo Flow pipes with a Oase biomaster2, my first time with a canister filter. I like the look of clear pipes and didn’t want to worry about breaking glass, the PETG feels durable and it easy to cut. I also added the Neo outlet, so I can’t really comment on the flow control outlet, as well as adding the Neo inlet with the small holes. Instructions mostly rely on pictures, but set up is not hard to figure out. The skimmer takes some time and fiddling to get adjusted right, and doesn’t take much to get clogged or affected by water level. I do like it being on the outlet, and it does help catch some plant debris. Overall really happy with the Neo Flow lily pipes."

These lily pipes look amazing

"These lily pipes look amazing in my tank."

Justin P. (5/5)

Another winner from Aquario Neo

"This is a cleverly designed little gadget! It installed easily onto my aquarium's lily pipe and, so far, has worked perfectly. The CO2 bubbles are so fine they're hardly noticeable, and they don't seem to sprint to the surface as quickly as those produced by conventional diffusers. It's been working for a week now, and in that time my plants have enjoyed a nice little growth spurt!"

John M. (5/5)

Does exactly what you need it to do

"I like this piece. I initially purchased the neo flow pipes because the neo reliever + PETG + skimmer on the outflow sounded like a gnarly combo. Then I got into high tech scaping and realized I needed strong directional flow to circulate the CO2. I didn’t want to buy new expensive pipes at the time so this piece came in clutch. Honestly, the diffusion is much better than I expected, considering how simple the shape is. The shape is not as fine tuned as ADA tier pipes (obviously), but they get the job done pretty well. It also comes with a little flow diffuser piece that snaps into the inside of the bulb which is dope. It’s nice to have a modular lily pipes on the market because the hobby’s crazy obsession with minimalism can be brutal for people who can’t afford to casually keep a closet full of expensive paperweights."

Matthew H. (5/5)

Clean looking and functional

"Easy to install. Looks very clean on my 60U setup. I'm not using the reliever but replaced with the neo outlet. With this setup flow seems great and seeing movement around entire tank including the carpet."
