My alk rised a little?

[Notsolostfish]

I ran out of water for the awc, im gonna make water this week, noticed a rise in my alk tiny bit like 8.45 to 8.65. And same for calc 440-460. Why would stopping awc makes my parameters rise a little bit?

I wouldn't worry about this. You can do tests back to back and get those results.

The change is so small, it isn't likely that the auto water changer drying up is responsible.
