How can I keep my ph up?

[Borderjumper]

I think it was a infamous reefer that once said something like this:

The best way to keep your PH up is to throw away the PH test kit and not worry about it.

I used to stress about my PH being 7.9. I would buffer it up and the next day it would be back at 7.9. Well I stopped trying. It wants to 7.9 so I let it be 7.9. You saw my stuff, non of it minds 7.9PH
