Quick question, how much ph does 1 gram of sodium hydroxide and how much alkalinity will increase along with ph.
 
Tank size in gallons or liters is needed.
 
If you instantly add 1.4 dKH of alk with hydroxide, then for seawater with an alk around 7 dKH, pH will rise about 0.65 pH units. If you spread that addition out over many hours, the pH rise will be far smaller (with the same total alk rise).

Can shifting my sodium hydroxide 2-part dosing schedule help stabilize pH swings? Will it be at the cost of stable alkalinity?
