Aerating coolant, do I need a "stone" or not

If the stone does get plugged with coolant residue, would soaking the
stone in vinegar unplug it?
Unless it clogged rapidly, I'd just replace it. Hell! Those things are
about $0.30 at ChinaMart.

I've had one running for an hour a day for about the last 6 years and
the stone isn't plugged, still works fine. A skimmer is a thought on the
todo list.
