I have seen a couple questions about ice making with brine, I know nothing about it and was hoping for some info.

1. Air is blown into the can when making ice to:
Remove bubbles
Purify water
Speed up ice making
Is never done

2. Air is blown in formaking clearer ice.-right?

When ice making the brine flows;
In the shell
Around the shell
through the tubes
around the tubes

The water level around the cans in ice making should be;

below the water level in the can
above the water level in the can
at the same level as the water in the can
thanks, alot of my recent post have been question for my masters, I am ready to be done with this chapter of life.
