How to straighten polyethylene tubing?

[Miami Reef]

It’s curving up but I want the tubing to reach the bottom of the dosing container. I don’t want the tubing to pop out and not dose any liquid.

How can I make it down?

Hold it in boiling water for a few seconds then lay it flat with something on each end till it cools and holds that straight shape. Just did this today with vinyl tubing!

Either this ^^ or use a heat gun or hair dryer.

Yep, heat it up, straighten it, hold it and cool it.

Sounds like a neat new dance move
