Aeration to re-activate stabilized chlorine?

Got a roughly 17k gallon in ground pool.
Have been using chlorine/CYA tablets for the last 3 years or so. Pool is left open and green over winter, no CYA expected overwinter.
Pool has a sand filter, is filled with very hard well water.

This year, I stared occasionally diverting the water return through a single large pipe as a fountain, initially this was meant as a quick way to raise the water temperature in May.

However since then, I have noticed that running a fountain helps with chlorination of the water. Just re-ordered pool test kit, only have observations at this point, no actual numbers.

My initial review suggests that aeration driving the pH up is the cause.

It seems that slightly raised pH should result in more active chlorine, or less active CYA stabilizer molecules, effectively increasing chlorination, without actually adding more chlorine

Other idea is that aeration during a sunny day is breaking down/ driving off chloramines in much the same manner as superchlorination is supposed to.

Curious whether anybody has done any actual testing or had any experience with the mechanism of pool aeration on increasing available chlorine and water clarity?
