Taking the Salty Plunge!

[Chemi]

I added another rock where you recommended, I like the way it looks now. Thanks!
So I have a small problem. I mixed up my I stand Ocean salt, and my parameters are slightly off. My SG is 1.0255 and my pH is 7.74. How can I increase my pH without adding to any other parameters? Like adding baking soda would add to the hardness but increase pH. Should I just purchase some 'pH up'? My test kits are in the mail receiving on Monday so these are the only parameters I know as of right now.
Thanks Guys!
