ATO Line weight

[chrisjj625]

Does anyone know of a weight for the bottoms of an ATO line to keep it at the bottom of the container?

I use a 4.5 Gal tuperware type container.  I drill a hole in the lid so the ATO return line is a tight fit and doesnt slide up or down without some force on my part.  It keeps my tunze ATO wherever i place it, usually about an inch from the bottom.
