Does anybody have good recommendations for installing a Dock Bubbler system?

This video on Youtube shows it pretty well:

DockBubblers System Installation - Dock Bubbler - Standard Straight Dock

Does this system use a pump or a compressor? (different websites refer to both)

Does it run around the clock or can it be run with a timer or wifi like circulators?

If the lines are full of air, and then stop, does water get in through the perforations and need to be emptied manually?

Do the weights keep the tubing in place where you want it or does it get pushed around by the compressed air?

Any thoughts would be great! Thank you in advance!
