Glass Lillie pipe DIY

The prototype for a glass lillie pipe came in the mail today. I contacted a scientific glass ware company to make the pipe for me. I will be placing a large quantity order to sell the glass return and supply in our auction area. The nipple for the suction cups needs to be reduced and the outlet lip would look better if it was more of an oval. If you are interested in making them DIY maybe contact local glass art stores, etc. I will post drawings that I made for the pipes later. I'm working on the return pipe and will get a prototype of that one next. The quantity order will be 16mm to fit more standard eheim tubing.

Hey .. That looks really nice! How far away are we from being able to purchase this? And how much are we looking at spending?

From all the feedback I have been getting from forums, it might be better to make them myself so that I can sell them for less. If I made a large order I could sell them for $30. They seem easy to make, just need to learn a new skill, and then I could sell them for less. Maybe make a kit that includes intake, outlet pipe, clear tubbing and clear suction cups.

Seems like a fragile thing to hang over the rim of your tank. I'd be worried to break it in no time...

Why? Most tanks are made of glass...

Of course, you'd need to be more careful with it than with standard plastic outlets, but good glass can be pretty strong.

Maybe see how much they would cost to be made with a stronger glass material. Maybe something along the lines of pyrex.

She uses "Duran Tubing 16mm OD x 2.5 mm wall. It is also a better quality glass."

Amano uses 1.7mm (I think, from what I've read), so I purposely made it thicker so it would be less delicate. Its pretty sturdy, but yeah you have to be careful with it. Intake prototype was ordered today. Will post pics when they arrive.

What is the benefit of using the lilly pipes? Better circulation? Not as visible? I have notice them in Amano tanks before but never knew what they were called? Thanks for any info.

That is very interesting, I don't understand the need for an energy dissipator though, I'd want a straight pipe entering the aquarium at least 1 inch below the water line and pointing down at 15░ angle for a shallow tank (12 inches) and stepping down 5░ for each 4 inches of added height so a 24 inch tank would have a 30░ bend. I think the energy dissipator takes away from a current that helps plants obtain CO2 and, for some plants, nutrients.

The above is just a personal observation, it's easy to sit back and critique, it's hard to do the work and make something usefull, keep up the good work, I think you'll have a nice product regardless of armchair developers like me.

It's a fine line between fishing and standing on the shore looking like an idiot.

That IS an aquascape, it's titled "The Vacant Lot".

I don't know much about duran tubing, but wall glass is very solid.
