It's better to get rid of the causes of your low or high pH than use a chemical fix that will at best only be a temporary fix and in the long run only compound the issues. Low pH is the result most often of the accumulation of CO2 in the tank water. If your tank's pH is chronically low, then first off it is best to check your meter (never rely on pH chemical tests or strips for this) to make sure it will pass the Borax test. If it passes the borax test, then remove any lids, covers, or snug fitting hoods to allow for good air exchange with the water surface. If your house is closed most of the day, then find a way to run a hose from outdoors to your skimmer's air intake, and use outdoor air (lower than indoor air for pCO2) to increase the gas exchange rate in your aquarium. This may require that you get a fan for your sump and some powerheads to push water from the bottom reaches of the tank towards the surface and to create some turbulance to increase gas exchnges as well. Try this initially to see how this affects the tank, especially if you test for your alkalinity and it is anywhere near normal for seawater.
It is unlikely that your tank willbe chronically high unless you're dumping in a lot of additives. What is the specific problem for your tank?

Definitive guides IMO
