Using the Molecular weights for your equation...
(84/61) * 21.8 = 30mg/L
84 is the molecular weight of Sodium Bicarbonate ( Baking Soda ), 61 is the molecular weight of the Bicarbonate ion, and 21.8 is the conversion of dKH in ppm of Bicarbonate ions (as in ... 1dKH= 21.8 ppm bicarbonate).
So, to increase the alkalinity by one dKH unit as you are hoping, using sodium bicarbonate, you'd need to add 30mg of Sodium Bicarbonate per liter of water to be treated.
160 gallons = 600 Liters.
600 x 30 = 18000mg of sodium bicarbonate. This is 18 grams of sodium bicarbonate ( 1000mg = 1 gram )
1 Tablespoon = 14.235 grams.
So....
To raise the alkalinity in your tank from 7.2 to 8.0 dKH using sodium bicarbonate, you would need to add 1.3 Tablespoons of Sodium Bicarbonate.
