More bubbles equals more D/O. You can use less, but you run a higher risk of nasties growing in the solution with less D/O in it.
I've seen succesful grows that use less bubbles, but air pumps are cheap & the plants do better with more bubbles.

By putting the airline through the bottom of the bucket I don't have to mess with it when lifting the lid. Also, elbows cause reduced airflow. So the amount of air coming out of the air stone drops fairly significantly for every elbow you put in the air line.

You could have an automatic fill control for the tanks by running a line to a bottle of solution suspended upside down above the tank; the as the tank solution level dropped, air would go in the line, allowing more solution to flow from the bottle to the tank. Alternatively, there are cheap float valves. Larger aquariums use all sorts of devices like that for controlling water level. Or the connection at the base of the tanks could be joined via one tube to a master solution reservoir at the same height as the tanks.

Yes it would be a simple deal to make the water fill automaticaly. But then it would be a pain to make the minor adjustments to the nutes.
What gets added to the top up solution is a little different each time. It all depends on what the plants need.

A drinking water filter would remove some of the nutes. So that wouldn't work.

Thanks for stopping by,
