Inlet & Spray Bar Kit
Spreads the outflow instead of blasting one corner.
A canister filter returning through a single nozzle blasts one corner of the aquarium and leaves the rest still. Spreading that outflow along a bar fixes both ends of the problem.

Why you'll love it
Made for happy, healthy pets
One jet is the wrong shape for a tank
A single outlet makes a fast lane down one side and a dead corner opposite, where waste settles. A spray bar spreads the same turnover evenly so the whole floor stays swept.
Gentler on fish that hate current
Bettas, fancy goldfish and gouramis fight a jet all day. The same pump through a perforated bar drops the local flow rate without reducing the actual filtration.
Cheaper than replacing the filter
Most people who find their canister too strong start shopping for a smaller one. Changing the outlet shape solves it for the price of a takeaway.
Good fit if
- Long-finned fish fighting a current all day
- Planted tanks needing even circulation rather than one fast lane
- Replacing a cracked or lost original intake or outlet
- Reducing surface splash and the noise that comes with it
Look elsewhere if
- Your filter uses a different hose diameter
- You need strong directed flow for river species
- Your filter is internal or hang-on rather than a canister
The problem with a single outlet
All the water a canister moves has to come back into the tank somewhere. Through one nozzle that is a concentrated jet, so you get a fast lane in front of the outlet and dead spots everywhere else. Fish crowd into the still areas, and detritus settles in them.
Spread across a perforated bar, the same volume returns as a broad gentle sheet. Nothing is fighting a jet, circulation reaches the corners, and waste stays in suspension long enough for the filter to collect it rather than settling behind the hardscape.
Which fish care most
Long-finned fish are the clearest case. A betta, a fancy guppy or a veiltail has a large surface area and poor swimming efficiency, and being pushed around all day is genuinely exhausting for them. Fish from slow water, including most gouramis and many tetras, are in the same position.
The opposite exists too. Hillstream loaches, danios and other river species want current and do poorly without it. If you keep those, the duckbill outlet or the plain nozzle is the better choice, and this kit still helps by letting you point the flow where you want it.
Fitting it
Sixteen millimetre inner and twenty-two outer is the common canister size used by Eheim and Fluval among others, but check yours before ordering, since a mismatched hose either leaks or will not seat at all. Measure the existing pipe rather than going by the filter model.
The bar can be cut shorter with a fine saw if it overhangs, which is worth doing rather than leaving it protruding. Cap the cut end, since an open end sends most of the flow straight out of it and defeats the perforations entirely. Adjustable clamps grip the rim, and it is worth checking them after the first week as they settle.
The intake matters as much as the outlet. A strainer keeps fish, shrimp and stray plant leaves out of the impeller, and it is the part that clogs first, which shows up as the filter sounding busier while moving less water. Check it whenever you notice the outflow weakening rather than opening the canister.

Good questions
Before you buy
Check the hose, not the brand. If your canister runs 16/22 mm tubing, which most Eheim and Fluval models do, it fits. If yours is 12/16 mm, this is the wrong size.
Yes. It is plain plastic tube, so a hacksaw shortens it to suit a narrower tank. Cap the cut end or the pressure escapes out of it.
Along the back glass, angled slightly at the surface. Pointed straight down it stirs the substrate; aimed at the surface it drives gas exchange without a rippling storm.
It suits 16 mm inner and 22 mm outer diameter hose, which is the common Eheim and Fluval canister size. Measure your existing pipe rather than assuming from the filter model.
Yes, with a fine saw. Cap the cut end afterwards, or most of the flow leaves through the opening rather than the perforations.
At the back glass in most tanks, which circulates water around the perimeter without a strong current where fish swim. Angle it slightly up if you want more surface agitation.
