My question is, do I need a stone on the aerator, or not. I am
concerned that the stone will eventually become plugged by coolant
residue. If bubbling water without a stone is a little less efficient,
I do not think that I care too much.

Any thoughts on this?

No experience on this. But if you ran the aerator continuously the
coolant would never get inside the stone, so the stone should never
get plugged by coolant residue.

If the stone does get plugged with coolant residue, would soaking the
stone in vinegar unplug it?
