First, unless you really know what you are doing, slow down and do some reading. It's an old saying around aquariums:
"Nothing good happens fast in a saltwater tank."
Take it to heart!
That said, do not bother to chase the pH level unless it is way out of line. Like below 7.5 or above 8.5. The pH is related more to the CO2 levels of the air in your house than it is to anything in the water. High CO2 in your air will make for lower pH and raising it by adding ANYTHING to the water is a very, very short term effect (as in hours!). Given you have a new tank and it probably isn't cycled yet (my assumption) you need to consider keeping water parameters in line by doing water changes for the next 3 to 6 weeks at least.
