I read the post about glass lillie pipes and those pipes look good but there is an alternative to the glass lillie. I used acrylic tube as my outake and intake pipe for my canister filter. I bent the 6/8" acrylic tube into a U-shape. It works very well, but you have to know how to bend the tube or it will not be a smooth bend. Once placed in the aquarium, it is not noticeable at all and it looks very neat and nice.

details:

They are extruded acrylic tubes, overall diameter is 6/8". Thickness of the wall of the tube is 1/8". From my little experience, 1/8" thickness is harder to bend but it comes out neat and better looking than if you try bending a 1/16" thickness tube. The secret to bending these tubes lies in the heating process. Most people would recommend using a heat gun to make a bend but the source of heat that I used in bending my tube was my stove. My stove measures about 12 inches in diameter, so that's a long enough length to heat up the tube for bending. I place a brick at each end of a stove, then the tube would lay on top of the bricks. Turn the stove on "high", as the tube is being heated, I'm constantly turning the tube, so that there would be an even heating of the tube, after about at least five minutes, the tube would become soft and bendable. Base on your own judgement of how soft the tube is and if it's bendable, if it is, take the tube away and bend it into a U shape. It would be easier to bend the tube into a U shape if you have something that is already in the shape of a U and just use that as a guide.

The intake tube is relatively easy. As stated above, it helps to have a form around which to make the bend. A steel spring inside the tube will help prevent kinks. It also helps to be able to cool the tube fairly quickly so that it stays in shape.

But the output 'S' shapes tube would be more difficult to form.

electric stove. I think gas stove would be much more difficult to heat because the heat is not evenly distributed.

Pineapple,
Steel spring inside the tube? Never tried that before. How well does it work? It would be hard to find steel spring that small. Where do you get your steel spring?

Some expandable cafe curtain rods have springs inside - open the ends and remove...

Have you also made the out-flow pipe too?

In NYC we have some excellent plastics dealers on Canal Street. They stock and sell acrylic / plexiglas in sheets and tubes of all sizes. But that is not going to be of much help to you in Geneva, is it?

you could buy it online or look up a plastic dealer in your yellow book.


Pineapple,
I'm making a new outflow this weekend. The one I have right now does not look very attractive, so this weekend I'm going to try your method.

Try to make a flare at the end of the pipe, similar to ADA Lily pipes. The flare helps to distribute the outflow around the tank.

Let us know how it goes. Sounds like something I may be able to try sometime....if I can find some acrylic dealers around here.

I have an Acrylic dealer near by (Tap Plastics), but they don't sell anything with 1/8" wall thickness. Bending the 1/16" wall tube is difficult as it collapses very easily. Also, using a curtain rod spring doesn't work real well as a bending spring as the tube tends to conform to the shape of the coil making it near impossible to extract the spring without cracking the tube.

Rock salt

I heard from someone who bends these tubes and packs it with rock salt to keep it from collapsing -- wish I could remember who that was...
