Safest and best way to raise PH

[CrystalClear]

I have been testing my water everyday and I notice that I am getting a constant reading of 7.0 of PH (or very close to it). I am think with going with some sort of cichlid tank, which I know these fish need a higher PH. Is there a preferred way to raise the PH over another? I know they sell the "PH up" liquid in stores. Is this a good stuff to use and will it remain stable?
