Here is what I posted to the other thread this am.

You want CO2 and H2S loss and the increase in DO (dissolved O2) by plants , wind (air interface) and water movement. What is your alkalinity? That is what buffers ph swings. Probably better to add ag lime.

With alkalinity of around 50 you are in good shape - could use a little lime. I would do nothing. Ph swings are normal.
