Temp and pH stability

[Velcro]

I know alk stability is king, and I do a good job of keeping that between 7.2-7.8 over a few weeks time.

I'm wondering about temp and pH. Our house is well insulated and consequentially has high CO2 levels. When windows are closed I'm still able to keep pH above 8 with kalk in the ATO and a co2 scrubber on the skimmer air intake.

The thing is that we are trying to cut back on AC use this summer so some days windows are open which causes the pH to go up more than usual, which some might call unstable.

Same with the temp, if windows are open instead of AC, the tank seems to heat up a bit from the T5 being on and then maybe be a degree or so higher the following night compared to the previous.

I'm attaching my apex logs. Do you guys see any issues here?

My ph swings from 8 to 8.3 so you should be fine there. Temp swing from chart goes from 77.5 to 80.1? That is a bit of a swing, do you have a fan set up to apex to try to cool before it hits 80? The swing isn't terrible and shouldn't harm anything but better to keep it as low as possible. Mine goes from 78.7 to 79.3
