My AWC lines are floating.. how do I fix this?

[Schulks]

These rodi lines are floating. How do others setup the fill line so it stays at the bottom?



I tied these acrylic rods to the fill lines to weigh it and keep it straight but it only half worked.



I think I'm going to attach a 1/2" pvc pipe to the entire thing to weigh it down more.

I glue a small piece of rock rubble to mine.

I found my pipe. I wanted something inert.

Using tubing heavier than water is also an easy solution. :)
