I would add 2 tablespoons (6 teaspoons) and it takes time. It might also be wise to do a good size water change just to account for any beginning imbalance of ions (low magnesium or high bicarbonates for example). Kalk works to slowly raise pH by raising alkalinity and it does this two ways, the free -OH and by binding to free CO2 to form carbonates. In general it takes at least a month of steady dosing to see a real difference in pH stability.
