I don't know if any of you have done this already, but I wanted to share anyway.
This is the Pico cleaner 2012.
My pico is bare bottom and I have struggled with getting airline tubing down to the bottom without overflowing my tank. With rigid tubing attached to soft airline tubing, gunk siphoning is a breeze.
How I did it
Get some 3/16 thin walled rigid tubing
some airline tubing
a heat source (I used a lighter)
A pill bottle
Heat the rigid tubing just a little so it is pliable, then mold your bend over the pill bottle. Cut tubing to necessary length, then attach airline tubing.
