Weekly testing, and the use of a commercial buffer to raise it. If you're looking for a product name, one of my favourites is Seachem Reef Buffer 8.3 which helps keep a higher pH. If you have a fish only tank it isn't as important, but if you have corals you should try to keep your alkalinity within a 1 dKH (less than 20 ppm) swing, so this may require dosing more than once a week.
