Thanks Fire, those look good.
Do you clamp the bag over a perforated pipe (like putting your foot in your sock), or do you just clamp the opening on your pipe and let the bag hang?
When transferring water, do you use them in the air over a splash pad or submerged in the receiving pond?
Finally, are you running your water transfers on gravity, or hitting the bags with more force - like a siphon or pump discharge?
