The pix and the video are gone. Bummer, because this was one of the most useful DIY threads I've ever seen. The pipes looked great and avoiding the risk of glassware cracking by using acrylic really made this topic useful.

onefang has a video on youtube for the lilly pipes, though I understand.

I found the video on the APE (aquatic plant enthusiast) website. It pretty much consisted of a person using a heat gun mounted on a table to heat a rod he was constantly spinning and bending little by little.

That's about all there is to it. I wish I could see the drop checker, though.

I haven't seen the video, but believe you fill the tube with fine grain sand to prevent the tube from losing it's shape and volume while bending. At least this is the way I have seen it done before in other applications.

This a great DIY. And just in time for a project I have in the works!

Has anyone tried flaring out the end of the tube to imitate the ADA lily pipes? I may have to try just see how it turns out.

Was the drop checker in the missing photos or am I just not seeing it?

filling the tube with sand or something is a good idea. As far as the flaring, from what I remember in the video, he heated one end, piched it **** with some pliers and then blew into it to create a bubble. Then he cut part of the bubble away to creat the flared end.

I want to preface this post by stating that this is not an advertisement for custom pipe sales. Nor is it in any way intended to get PMs for custom work or sales in any way. This is purely for the informational value, and to help others who'd like to give this a shot.

Just wanted to share some of the lily pipes, drop checkers, etc, that I've made.
I had a video up here a while ago that was a basic walkthrough on how to bend acrylic tubing, but it somehow got deleted. If anyone is still interested in a brief walkthrough on bending acrylic tubing, for making lily pipes, filter hardlines, drop checkers, etc, let me know and I'll do another short video on the matter.

The basic process is mostly a matter of heat control and patience. I've tried fillers from sand, flour, to silicone tubing, and nothing seems to get quite the same results as bending the tube freehand.

I use a 1500watt heatgun that I've modified to sit pointing straight up(like a burner), and bend most of my tubing(6mm, 10mm, 13mm) on it's low setting. Heating about a two inch portion of tubing at a time, I make very minute bends, using my fingers to keep the hot tubing in shape.

For the lily cups, I get the end of the tubing hot and pliable, and then seal it off by pinching it with pliers.
I then heat a 2" section just behind the sealed end. Once very pliable, I blow a bubble in the tubing, and hold pressure until the tubing is cooled. I then cut the bubble diagonally in a hobby miter block, with a very fine toothed razor saw.

Here is some of the things I've made(for myself, and for others):

13mm Lily Pipe


10mm Hang-On-Tank Lily Pipe


13mm Clear Eheim replacements


10mm ADA style nano pipes


Hang-On-Tank Drop Checker


Another H-O-T DC, curved to match the ada style nano pipes


10mm nano pipes, in use on buddy Zeldar's tank:


Crazy 10mm pipe set I made for dxiong5, upturned intake so filter sponge will stay in place
(a design originally devised by msnikkistar)


Aimable spraybar in 13mm for 7.5g cube that I made for beedee


Another aimable spraybar in 13mm for standard 10g, also made for beedee


That's about all the pics I have right now. If anyone has any questions, I would be more than happy to answer!

These are absolutely fantastic. I tried looking up the youtube post but it seems like it is no longer available. Could you please message me when you have a chance. I have a few questions.
