Thanks Robert and others that have helped inform me.

What was the little air pump form graingers do you
remember?  What was the air flow?  

About what size air holes did you drill in the bucket?
How did you get the small air bubbles? 

How did you weight down the polytube?

Thanks again to all 
Daryl
