DIY Acrylic Lily Pipes

So, I'm considering fabricating some DIY lily pipes for my Fluval 405. After doing research, I found that the hose for this filter is 5/8" ID 3/4" OD. I have acrylic hose btw, not the stock hose.

Based on those measurements, what is the proper size acrylic pipe I should get? I assumed 3/4", but wasn't sure if that is right. I figured the filter hose would fit into the acrylic pipe. If anyone's done this before, could you help me out? Thanks!

You would go the other way (i.e. buy acrylic tube that has a 5/8" OD). The pipe would go inside the hose.

Hope this helps.

Ah, so the lily pipe goes inside of the hose? Gotcha. I'm gonna order some acrylic pipe online since Home Depot didn't have any. Thanks!

Find out if you have any plastic manufacturers in town. I saved a ton on shipping by finding a local place

Its really hard trying to blow the bubble in the beginning. You probably need 12 ft of tubing if you are unexperienced. I popped almost 5 ft of tubing already

Haha good to know! I'll grab 12 ft so I have some trial and error room. How many feet do you use at a time for one pipe?

About 1. For larger pipe I would say a bit longer.

I experienced putting the tube insede the lily and no leaking occured, is there any other reason to put the lily inside the tube instead of the way i did it?

Here is how the lily pipes look like with the tubing going inside,
The flow didnt suffer, and i measured the flow with and without the lilys,
1.3liters in 15 seconds without the lily and 1.5liter in 15 seconds with the lily

No leaks even without any vaseline or silicone.

Cyandier - I've been making these pipes for a couple years and they still aren't easy to make. I've probably made 200+ sets. 5/8" OD acrylic is the absolute largest you can bend by hand without a mold unless you don't mind the hose being kinked up.

"I experienced putting the tube insede the lily and no leaking occured, is there any other reason to put the lily inside the tube instead of the way i did it?"

That was more than likely a glass pipe that you did that with. Acrylic will crack and creep until it leaks if you do it that way. Tried that method; it doesn't work with acrylic.
