Is this a dramatic pH swing???

[TDTA1181]

I know your not suppost to chase pH numbers but i don't currently run a reverse lt. schedule in my sump and my pH according to Apex is 8.18 in day time and reading 7.93 @ night. I usually calibrate the probe ever 3 months or so.

Looks good to me. I wouldn't worry about it.

No, that swing is neither especially large, nor is the low end a concern (which is most often the concern with pH).

that's not much of a daily change IMHO

+2, my tank pH swing is about the same as yours.
